Question

Two pieces of length 5 6/7 m and 2 6/7 m
are cut off from a rope 20 m long. What
is the length of the remaining rope?​

Answer 1

Step-by-step explanation:

let the length of remaining rope is x

then x+5 6/7 +2 6/7 = 20

x+41/7 +20/7 = 20

x + 61/7 = 20

x = 20-61/7

x = 140-61/7

x = 79/7
