Question

Mother bought 13/6 kg of sugar. She used 5/6 kg while baking cookies. How much sugar did she have left?

a)18/6


b)18/12


c)8/6


d)8

Answer 1

Answer: c) 8/6

Step-by-step explanation:

Both 13/6 and 5/6 have the same denominator 6.

Subtract the numerators: 13-5 = 8

This is the numerator of the final answer 8/6. The denominator stays the same when subtracting fractions.

Optionally we can reduce 8/6 into 4/3, but it appears your teacher is leaving it un-reduced.

Side note: 4/3 = 1 & 1/3
