Question

Traci has four blue pens and three red pens. She has twice as many black pens as blue pens. What fraction represents the number of blue pens out of the total number of pens

Answer 1

The total is 4+3+8=15
The answer would be 4/15 because there are 4 blue pens

Answer 2

4 blue, 3 red
twice as many black pens as blue pens.....black pens = 2(4) = 8

so there are : (4 + 3 + 8) = 15 total pens

fraction of blue pens to total pens = 4/15
