Question

divide 8/27 by the sum of 2/3 and 7/15​

Answer 1

Lcm of 3 and 5 is 15 so,

2/3 + 7/15 = 10/15 + 7/15
= 17/15

8/27 divided by 17/15

So, we reciprocal the number on the right which makes,

8/27 * 15/17

*cancel 27 and 15*

= 8/9 * 5/17 ( here nothing can be canceled so we multiply them )

= 40/153

This answer is 40/153

Hope it helped :)
