Tony has 7/8 of a candy bar. he wants to split the bar into servings that are 3/10 of the bar. how many servings can he make?

Answers

alright, so let's make both 7/8 and 3/10 into fractions with the same denominator.
The lowest common denominator for both of these is 80.
So, we multiply the top and bottom of 7/8 by 10, and the top and bottom of 3/10 by 8 to get fractions we can compare.
So, we have 70/80 of a candy bar, and we want to make servings of 24/80 each.
How many times can 24 go into 70? 2 times, with a remainder of 22.
So, Tony can make 2 servings.

Ky wants to buy three shirts, which were originally priced at $49.96 each. How much will the three shirts cost before tax?

Answers

Final answer:

To find the total cost of three shirts priced at $49.96 each before tax, multiply the price of one shirt by three, resulting in a total of $149.88.

Explanation:

The question concerns the calculation of the total cost of three shirts before tax in Mathematics.

To answer it, we simply need to multiply the original price of one shirt by the quantity desired.

Since one shirt is priced at $49.96, the cost for three shirts can be found by performing the following multiplication:

$49.96 × 3 = $149.88

Therefore, the total cost of three shirts before tax is $149.88. This calculation is a straightforward example of applying basic multiplication skills to find the total cost of multiple items.

Thus, for the given value of originally priced at $49.96, the cost  before tax is found to be $149.88.

martin has 18 coins, all dimes and quarters, worth $2.85. how many dimes does he have

Answers

Since 1 quarter equals 25 cents, 3 will equal 75.

Then how do you get 85?

Well 75 + what ( x ) is 85?

Or 85 - 75 is what?

85 - 75 is 10.

10 cents is a dime. So add a dime to it. So now you have a total of 4 coins. You need to find the leftover 14 coin values.

So, 10 dimes is a dollar and 4 quarters is a also dollar.

10 + 4 is 14 and a dollar + a dollar is 2 dollars.

2 dollars + those 4 coins, 85 cents is $2.85.

You`re final answer is : Martian has 11 dimes and 7 quarters.
