Question

10% of an amount is 6.2 . Wirk out the original account
​

Answer 1

the original amount was 62

Explanation:

You can use the part over whole formula like this:

`(part)/(whole) = ( (6.2)/(?) * (10)/(100))\\ ? = 62`

why?

because we know that 10% = 10/100, we can easily find out the answer by cross multiplying

? * 10 (let's use x, instead of ?)

=10x

6.2 * 100

= 620

Now we have an equation that looks like this: 10x = 620

By using the inverse operation tool (dividing each side by 10 to isolate x) we have:

x (or ?) = 62
