Answer:
A) He used 2/3 yard of wire
B) He had 4/15 yard of wire left
Step-by-step explanation:
An electrician had 14/15 yard of wire
He used 5/7 of the wire
A) How many many parts of wire did the Electrician use?
This is calculated as:
5/7 of 14/15 yard of wire
= 5/7 × 14/15 yard
= 2/3 yard of wire
He used 2/3 yard of wire
B) How many yards of wire does the Electrician have left?
This is calculated as
14/15 yard - 2/3 yard
Lowest common denominator is 15
Hence:
14 - 10/15
= 4/15 yard of wire left
