Question

A hardware store has 10 metres of nylon rope. In the morning, a customer buys 1/5 metre of rope
from the spool. In the afternoon, another customer buys 7/10 metre of rope from that same spool.
How much rope is left?

Answer 1

Answer:

Step-by-step explanation:

Length of rope initially present in the store = 10m

length of rope bought by the first customer = 1/5m

length of rope bought by the second customer = 7/10m

length of rope left = 10 - {1/5 + 7/10}

                                = 10 - 0.9

                                = 9.1m
