Question

Workout and simplify where possible a)2/5 + 1/3
B) 5/9-1/2

Answer 1

Answer:

A).

2/5 + 1/3

First find the LCM of the denominators

The LCM of 5 and 3 is 15

Add the fractions

We have

$\frac{2}{5} + \frac{1}{3} = \frac{2(3) + 5}{15} \\ = \frac{6 + 5}{15} \\ = \frac{11}{15}$

B.)

5/9 - 1/2

Find the LCM of the denominators

LCM of 9 and two is 18

Next

Subtract the fractions

We have

$\frac{5}{9} - \frac{1}{2} = \frac{5(2) - 9}{18} \\ = \frac{10 - 9}{18} \\ = \frac{1}{18}$
