Question

Nancy does 5 loads of washing per week using a box of a 1.2kg box of Fab using 60 grams per wash.How many weeks should the box of washing powder last.

Answer 1

So 1.2 Kg = 1200 g
5 washes per week = 60 grams x 5 times = 300 grams per week
1200 grams total divided by 300 grams per week
= 4 weeks

So the answer is 4 weeks
