Question

answer the following 1/7+5/7-7/8=​

Answer 1

Answer:

1/7+5/7-7/8 = 6/7 -7/8

LCM of 7 and 8 is 56.

so, 6/7 - 7/8 = (6×8)/56-(7×7)/56

=48/56 - 49/56 = -1/56

hence,your answer is -1/56

Answer 2

Answer:

-1/56

Step-by-step explanation:

• 1/7+5/7=6/7

(as denominator is equal)

• 6/7-7/8= -1/56

(denominator is not equal so LCM of 7,8=56, and in numerator 6×8=48,7×7=49)
