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
