Question

22/7+ -5/14 + -7/12 + 23/4​

Answer 1

Answer:

167/21

Step-by-step explanation:

The signs can be simplified as:

22/7+23/4-(7/12+5/14)

The LCM of 7,4 is 28 & the LCM of 12,14 is 84.

1. (22*4+23*7)/28 - ((7*7+5*6)/84)
2. (88+161)/28 - ((49+30)/84)
3. 249/28 - 79/84

The LCM of 28,84 is 84

1. 249*3/84 - 79/84
2. 747-79/84
3. 668/84

Cutting by 4, => 167/21

This is equal to 6 1/21{Mixed Form} or (167/21).
