What is 62.5% as a fraction in simplest form

Answers

Answer:

5/8

Step-by-step explanation:

The required simplest form of 62.5% is 5/8.

Given that 62.5%.

To express a% as a fraction in simplest form, we divide a% by 100 gives,

a% = a/ 100

For example, if a = 75%, gives:

75% = 75/ 100

Simplifying the fraction:

75 / 100

To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 25:

75 ÷ 25 / 100 ÷ 25

This gives:

3/4

Thus, 75% as a fraction in simplest form is 3/4.

Consider the example of 62.5%.

To express 62.5% as a fraction, divide 62.5% by 100:

62.5% / 100

Simplifying the fraction:

62.5 / 100

To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 12.5:

62.5 ÷ 12.5 / 100 ÷ 12.5

This gives:

5/8

Therefore, 62.5% as a fraction in simplest form is 5/8.

11 less than three times a number is the same as 75 less than the product of -1 and the number

Answers

Inequality?

11 < 3x = 75 < -1x

11 less than (-11) 3 times a number (3n) is the same as (=) 75 less than (-75) the product of -1 and the number (-1 times n or -n)

-11+3n=-75-n
solve
add n to both sides
-11+4n=-75
add 11 to both sides
4n=-64
divide both sides by 4

Blueberries are on sale for $2.80 per pint. The regular price is $3.50 per pint.

What is the percent of decrease?

Select from the drop-down menu to correctly complete the statement.

Answers

20% decrease. Divide 3.5 from 2.8 to get 80%. then you subtract 80% from 100% to get 20%.

Answer: The percent of decrease= 20 %.

Step-by-step explanation:

Regular price of blueberries= $3.50per pint

Current selling price=$2.80 per pint

Clearly, there is decrease in price as 'Current selling price' < 'Regular price'

Now, Decrease in price=Regular price-Current selling price

[tex]=\$3.50-\$2.80=\$0.70[/tex]

We know that Decrease percentage =[tex]\frac{\text{Decreased price}}{\text{Regular price}}\times100[/tex]

[tex]=\frac{0.70}{3.50}\times100\\=\frac{7}{35}\times100\\=\frac{1}{5}\times100\\=20\%[/tex]

Therefore, the percent of decrease= 20 %.

Answers

57.10
70.9
these are only the answers for the first two problems

1) Convert fraction into a decimal: 4 / 7 = 0.5714... Round to nearest tenth. The 5 is in the tenth place. Look at the digit on the right of 5. Is it equal or greater than 5? Yes. 7 is greater than 5. We round up to 0.60. Convert decimal to percent: 0.60 => 60%

2) Just move the decimal point two places to the right: 0.709 => 70.9%

3) We know that 1/3 is equal to 33 1/3%. Just multiply 33 1/3% by two.

0.333... * 2 = 0.6666... = 66 2/3%

4) Alice gets 21 free throws and makes 81.25% of them. The question then asks "how many free throws she makes". Well just multiply 81.25% by 21:
0.8125 * 21 ≈ 17

5) Convert percent into decimal: 48% => 0.48
Multiply: 0.48 * 23.95 ≈ $11.50

6) Multiply 15% by 58.50: 0.15 * 58.50 ≈ $8.80

1) Painting on a Wall: Painters use ladders to paint on high buildings and often use the help of Pythagoras' theorem to complete their work. The painter needs to determine how tall a ladder needs to be in order to safely place the base away from the wall so it won't tip over. In this case the ladder itself will be the hypotenuse. Take for example a painter who has to paint a wall which is about 3 m high. The painter has to put the base of the ladder 2 m away from the wall to ensure it won't tip. What will be the length of the ladder required by the painter to complete his work?

2) you need to come up with a drawing for it.

3)You can calculate it using Pythagoras' theorem:

(5)2 + (2)2 =

$105 skateboard; 7 1/2% tax

Answers

The total will be 183.75.

So 7&1/2 and equal to 7.5% And when it is a percentage, you move the decimal two places to the right. So it would be 0.75%.

Therefore, we time 0.75 and 105 together to see how much is the tax.
0.75*105 =78.75

Then we add 105 and 78,75 together to get the totally amount pay.
105 + 78.75 = 183.75

So the total is 183.35.

Or you can do it like this:

Fiona eats 75 grams of trail mix. How many calories does she eat? If 50 trail mix= 150

Answers

150/50=3 calories a gram
3×75=225 calories

Final answer:

To find out how many calories are in 75 grams of trail mix when 50 grams contain 150 calories, set up a proportion and solve for x. The calculation shows that 75 grams of trail mix contains 225 calories.

Explanation:

If 50 grams of trail mix contains 150 calories, to find out how many calories are in 75 grams of trail mix, we need to set up a proportion since the relationship between the weight of the trail mix and the calories it contains is a direct one. This means that if the weight goes up, the calories will also go up by the same rate.

To calculate the calories in 75 grams of trail mix, we use the following steps:

Understand the given information: 50 grams = 150 calories.Set up a proportion to find out how many calories are in 75 grams:

(50 grams / 150 calories) = (75 grams / x calories)

Cross-multiply to solve for x (the number of calories in 75 grams):

50x = 75 * 150

Divide both sides by 50 to solve for x:

x = (75 * 150) / 50

x = 225 calories

Last week, Chen bought 8 1/2 gallons of gas at $2.30 per gallon. This week, he bought 4 3/10 gallons of gas at $2.70 per gallon.

What was his total cost?

Answers

The total cost of the gallons of gas will be $31.16

Since Chen bought 8 1/2 gallons of gas at $2.30 per gallon, the cost will be:

= 8 1/2 × $2.30

= 8.5 × $2.30

= $19.55

Since he also bought 4 3/10 gallons of gas at $2.70 per gallon, the cost will be:

= 4 3/10 × $2.70

= 4.3 × $2.70

= $11.61

Therefore, the total cost will be the addition of both values gotten and this will be:

= $19.55 + $11.61

= $31.16

Therefore, the total cost is $31.16
