Question

find 3 /7 + ( – 6/11) + (–8 / 21) + 5 / 22

Answer 1

Hola

Here is your answer


3/7+ (-8/21) +(-6/11) +5/22 ...By
commutative property

so,

Lcm of 7 and 21 is 21
Lcm of 11 and 22 is 22

thus,

3×3/7×3
=9/21

and
-8/21


-6×2/11×2

= -66/22


therefore,

9/21 - 8/21 -66/22+5/22

= 1/21 - 61/22

Hope it helps
