Question

7/6 - (-2/9 in simplest form

Answer 1

It is a mixed number of 1/7/18

Answer 2

7/6 - (-2/9)

When multiplying a negative by a negative, you always get a positive, so our new problem looks like this : 

7/6 + 2/9

Make 18 the denominator by multiplying 7/6 by 3/3 and 2/9 by 2/2.

$\frac{7}{6}$ + $\frac{3}{3}$ = $\frac{21}{18}$

$\frac{2}{9}$ + $\frac{2}{2}$ = $\frac{4}{18}$

NEW PROBLEM : $\frac{21}{18}$ + $\frac{4}{18}$ = $\frac{25}{18}$ 

That simplified is : 1 $\frac{7}{18}$
