1.

7/90.

This is become 0.7... is tenfold of 0.07...

I just divided by 10 on 7/9.

7/9 ÷ 10 = 7/90

The second one is a little more difficult.

Let X equal the decimal number

Equation 1:

$$X = 0.4\overline7$$

$$10X = 4.\overline7$$

Subtract equation (1) from equation (2)

10X - X = 4.3

9X=4.3

X = 43/90

I hope this helped,

Gavin
