72:64 = 9: ___
what is the answer?

Answers

The equivalent ratio is calculated as: 9:8

How to find the ratio?

Ratio is defined as the relative size of two quantities expressed as the quotient of one divided by the other; the ratio of a to b is written as a:b or a/b.

Proportion is defined as an equality between two ratios.

We are given that the ratio is 72:64.

This is equivalent to 72/64

If the numerator is broken down to 9 it means the denominator will be divided by 8 to get 64/8 = 8.

Thus, the equivalent ratio is 9:8

Nine tenths of a sum of money is 45. Find the whole amount

Answers

If you would like to know the whole amount of money, you can calculate this using the following steps:

nine tenths of a sum of money is 45
9/10 * x = 45     /*10
9 * x = 45 * 10   /9
x = 45 * 10 / 9
x = 50

Result: Nine tenths of 50 is 45.
The answer is 50.

First do 45 divided by 9 which is 5 then times by 10 results in 50.

A way to check this is by then finding 1/10 of 50 which is 5 then X by 9 is 45, which is what you originally started with.

In a game, a contestant had a starting score of one point. He tripled his score every turn for four turns. Write his score after four turns as a power. Then find his score.

Answers

If you start with one point and triple it, you get 3. And three tripled is nine, and nine tripled is 27. And 27 tripled is 81.
1) 3

2)9

3) 27

4) 81

So writing his score after four turns is simple. 3 tripled four times is 3 to the fourth power, wich as you can see from above is 81.
