Answer 1

Answer:

1. $\frac{2}{15}$ - $\frac{1}{30}$ = $\frac{4 - 1 }{30}$ = $\frac{3}{30}$ = $\frac{1}{10}$

2. let the rational no. be x

x +  ($\frac{-3}{13}$ ) = -3

x - $\frac{3}{13}$ = -3

x = -3 + $\frac{3}{13}$

x = $\frac{-39 + 3}{13}$

x = $\frac{-36}{13}$

3. -7ki power 10 ÷ -28 ki power 10

- 7 ÷ -28 ki power 10-10

$\frac{1}{4}$ ki power 0

= 1

3. -4 ki power -3+7

-4 ki power 4
