What is 70% of 20. Also how did you get that answer ?

Answers

70% of 20 = 14

We can solve this by simply turning 70% into a decimal/fractions.

70% = $(70)/(100)$ = 0.7

Now you are going to multiply 0.7 by 20.

0.7 × 20 = 14

So your final answer is going to be 14.

- Well umma show you how to do it .

- if you need to find out what 10% is to find 10% you need to

20/10 =2

therefore 10% =2, Now that you know that 10% can work out the 70%

If 10% =2 than you will have to ↓

10·7 =70% whatever you do to the left side have too do to the other side. So, that means u also have too

Do 2·7 which would leave me ↓

70% =14 HOPE ThIS HELPS IF NOT COMMENT

So, the answer is 14
