Dina added five-sixths of a bag of soil to her garden. Her neighbour Natasha added eleven-eighths bags of soil to her garden. How much more soil did Natasha add than Dina?
We need to make the fractions the same. The LCM of 6 and 8 is 24, so
5/6 x 4 = 20/24, and 11/8 x 3 = 33/24,
We need to subtract them, so
33/24 - 20/24 = 13/24
