Question

Mika has three and seven - sixteenths cm wire.She needs only two and five - eights cm wire for her project in TLE .How much wire does she need to cut?

Answer 1

13/16 cm wire

Explanation:

Length of wire that Mika has H = 3 7/16 cm = 55/16 cm

length of wire that she needs N = 2 5/8 cm = 21/8 cm

Total length of wire she has (H) is the sum of total length that she need (N) and the length that she cuts (C). This can be expressed as;

H = N+C

Length of wire she needs N = H-C

Substitute the given values into the expression;

N = 55/16 - 21/8

Find the LCM

N = (55-42)/16

N = 13/16

Therefore she needs thirteenth-sixteenth cm wire
