Answer:
7.) n= 5
8.) n = 15
9.) n = 25
10.) n= 9
Step-by-step explanation:
7. 11:n = 33:15
11/n = 33/15
11*15 = n*33
165=33n
n = 165/33
n= 5
8. n:30=1:2
n/30 = 1/2
2(n)=30*1
n = 30/2
n = 15
9. n:40 = 5:8
n/40=5/8
8(n)= 40(5)
8n = 200
n= 200/8
n= 25
10. n:6 = 36:24
n/6 = 36/24
24n = 36(6)
24n = 216
n= 216/24
n=9
