Step-by-step explanation:
Ratio of time spend by Timothy while doing math, english, history, and social studies homework :2:2:3:1
Let the time spend doing math home work be 2x
Let the time spend doing English home work be 2x
Let the time spend doing history home work be 3x
Let the time spend doing social studies home work be 1x
Total time spend by timothy = 2.4 hours
[tex]2x+2x+3x+1x=2.4 hours[/tex]
[tex]8x=2.4 hours[/tex]
x = 0.3 hours
Time spend doing math home work =2x = 2 × 0.3 hour = 0.6 hour
Time spend doing English home work =2x = 2 × 0.3 hour = 0.6 hour
Time spend doing history home work =3x = 3 × 0.3 hour = 0.9 hour
Time spend doing social studies home work =1x = 1 × 0.3 hour = 0.3 hour
