Question

Work out 72 cents as a percentage of 83 cents. *

Answer 1

Answer:

Brainiest me

Step-by-step explanation:

Start with an easier looking example to gain confidence.

What is 20 as a percentage of 80?

As a fraction, we have 20/80 = 1/4

To convert that into a percentage multiply by 100.

1/4 * 100 = 25%

So, the idea is easy, (and you probably knew it already).

It is no harder as an idea just because the numbers are less helpful.

What is 72 as a percentage of 83?

Follow the same simple routine.

As a fraction, it is just 72/83, (because 83 has no factors to cancel with 72)

To convert that into a percentage multiply by 100.

You could do long division, (to find 83 divided into 7200) if you are told you must, but using a calculator is the sensible approach.

72/83 *100 = 7200/83 ~ 86.75 %

Now that you have found out how to do even tricky percentages, try not to forget the "fraction times 100" idea as it could help in the next test/exam.

Answer 2

Answer: 7200/83 or 86.746

Step-by-step explanation:

We will follow the basic concept of turning a number into a percentage, which is:-

$\frac{x\\}{y}$ x 100 = %

So,

Here the answer would be:-

= $\frac{72}{83}$ x 100

= $\frac{7200}{83}$ or 86.746
