Question

Javien’s weekly allowance was $20 .This week,his mother gave him an additional 1/5 of his weekly allowance . Jane’s weekly allowance is 1/2 of Javien’s new weekly allowance. How much were they given altogether this week?

Answer

This is a Proportion question.

 

 

   Last week This week  Javen
  5u 6u 3u
  20    

5u = 20

1u = 20 ÷ 5 = 4

9u = 9 × 4 = $36

 

Note

When additional 1/5 is given,

last week = 5/5, this week is 6/5
