The ratio is John:Jack:Jane...4:2:1.  4+2+1=7.  There are 49 pieces in the pizza, so 49/7 = 7.  Therefore, John: 4 * 7 = 28 pieces; Jack: 2 * 7 = 14 pieces; Jane: 1*7 = 7 pieces.  28+14+7 = your 49 pieces of pizza.

The total of the ratios is 4+2+1= 7

Dividing the total number of pieces 49 by 7 gives 7

The given ratio is

John: Jack :Jane

4:2:1

John will get 4/7 *49= 28 slices

Jack will get 2/7* 49= 14 slices

Jane will get 1/7* 49= 7 slices

Jack ate 14 slices
