There is \(\frac{4}{5}\) lb of sand in the science supplies. If one scoop of sand weighs \(\frac{1}{20}\) of a lb, how many scoops of sand can Maria get from the class supplies?

We want to divide whole sand into scoops, so we have to divide 4/5 by 1/20. Lets do this
20 1 ​ 5 4 ​ ​ We know that if we want to divide 2 fraction we can multiply first by inverse of second fraction instead of dividing.,so: 20 1 ​ 5 4 ​ ​ 5 4 ​ ∗ 1 20 ​ = 5 ∗ 1 4 ∗ 20 ​ = 5 80 ​ = 16 scoops - its our result.

6, because 4/5 = 8/10 - 5/10 = 3/10 x 2 = 6/20 divided by 1/20 = 6 scoops ;
