VMariaS [17]

Alright, lets get started.

Suppose Francine made number of baskets = x

As given in question, Jane scored 4 times as many as Francine.

Means Jane has scored number of baskets will be = 4x

Jane and Francine made 20 baskets together, means

x + 4x = 20

5x = 20

Dividing 5 in both sides

\frac{5x}{5} = \frac{20}{5}

x = 4

Means Francine made number of baskets = 4

Hence Jane made number of baskets = 4 * 4 = 16 : Answer

Hope it will help :)

Stells [14]

After Martha ate 1/4 of the pie there is 3/4 left.

Edwin ate 1/4 of 3/4.

so multiply 1/4 and 3/4 ---> 1/4*3/4=3/16

to find the leftover subtract 3/16 from 3/4

3/4-3/16

12/16-3/16=9/16

Christina ate 1/3 of 9/16

multiply 1/3 by 9/16

1/3*9/16=3/16

find the leftover by subtracting 3/16 from 9/16

9/16-3/16=6/16
