1)split 36 into the ratio 5: 4
2)split 45 into the ratio 7: 2
3)split 112 into the ratio 5: 9
4)split 66 into the ratio 4: 7
5)split 42 into the ratio 5: 2
6)split 65 into the ratio 7: 6
7)split 99 into the ratio 4: 7
this is all the homework i got on my first day back

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

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
