Add the two ratio numbers together then divide the original by that.

Then multiply that answer by each ratio number.

1)Split 36 into the ratio 5:4

5+4 = 9

36/9 = 4

5*4 = 20

4 * 4 = 16

It is split 20:16

2)split 45 into the ratio 7:2

7+2 = 9

45 / 9 = 5

7 *5 = 35

2*5 = 10

It is split

35:10

3)split 112 into the ratio 5:9

5 +9 = 14

112 / 14 = 8

5*8 = 40

9*8 = 72

It is split 40:72

4)split 66 into the ratio 4:7

4+7 = 11

66/11 = 6

4*6 = 24

7*6 =42

It is split 24:42

5)split 42 into the ratio 5:2

5+2 = 7

72 / 7 = 6

5*6 = 30

2*6 = 12

It is split 30:12

6)split 65 into the ratio 7:6

7+6 = 13

65 / 13 = 5

7 *5 = 35

6*5 = 30

It is split 35:30

7)split 99 into the ratio 4:7

4+7 = 11

99 / 11 = 9

4*9 = 36

7 *9 = 63

It is split 36:63
