Hi

You may use MD or work using units.

Women: Men ----- 3:1

Women: Children ----- 1:4 -------3:12

The ratio for women is repeated in both set of ratios, so make it the same.

Adult: Children ----- 4:12 -------1:3

Thanks for your help.

Hi

Hope this helps.

Number of pears ----- 10 units + 20

Number of plums ----- 10 units

Number of pears sold ----- 2 units + 4

Number of plums sold ----- 3 units

Number of pears left ----- 8 units + 16

Number of plums left ----- 7 units

15 units + 16 ------ 46

15 units ------ 30

1 unit ------ 2

Number of plums left ----- 7 units ------ 14

Hi

Please confirm.

Is it Reb or Jane?

Whether we are looking for Reb’s spending or Jane’s spending, the logic is still the same.

You may work with MD or Units.

Draw 4 boxes to show Jane’s spending.

Draw (1 box + 45) + (1 box + 45) + (1 box + 45) to show Reb’s spending.

45*3 -----135

800 – 135 ------- 665

7 units ----- 665

1 unit------ 95

Please continue from here.
