Question

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

Answer 1

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

`(2)/(5) + (1)/(3) = (2(3) + 5)/(15) \\ = (6 + 5)/(15) \\ = (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

`(5)/(9) - (1)/(2) = (5(2) - 9)/(18) \\ = (10 - 9)/(18) \\ = (1)/(18)`
