Question

We need to know how to Convert the fraction into its decimal representation on level seven using step by step instructions. We especially need to know how to solve 1/7 in level seven

Answer 1

We want to convert our fractions in a way the denominators are potencys of 10. Let's start with the first one.

`(32)/(40)`

If we multiply both the numerator and denominator by 25, we're going to have

`(32*25)/(40*25)=(800)/(1000)=0.8`

Now, with the next fraction

`(12)/(48)`

Dividing both numerator and denominator by 12, we have

`(12)/(48)=(1)/(4)`

Again, If we multiply both the numerator and denominator by 25, we're going to have

`(1)/(4)=(25)/(100)=0.25`

For the next fraction, it is enough to multiply both numerator and denominator by 4

`(3)/(25)=(12)/(100)=0.12`

For the next one, we can again multiply both the numerator and denominator by 25

`(18)/(40)=(450)/(1000)=0.45`
