Answer:

Explanation:

3.
(3)/(16)=(x)/(12)

36 = 16x

9 = 4x

x =
(9)/(4)

4.
(x)/(120)=(1)/(24)

x =
(120)/(24)

x = 5

5.
(a-2)/(9)=(2)/(3)

3a - 6 = 18

3a = 24

a = 8

6.
(b+4)/(5)=(7)/(4)

4b + 16 = 35

4b = 19

b =
(19)/(4)

7.
(3)/(7)=(c+4)/(35)

105 = 7c + 28

7c = 105 - 28

7c = 77

c = 11

8.
(2c)/(11)=(c-3)/(4)

8c = 11c - 33

11c - 8c = 33

3c = 33

c = 11

9.
(7)/(k-2)=(5)/(8)

56 = 5k - 10

5k = 66

k =
(66)/(5)

12.
(c+1)/(c-2)=(4)/(7)

7c + 7 = 4c - 8

7c - 4c = -15

3c = -15

c = -5

13.
(v)/(4)= (7)/(8)

v =
(7)/(2)

14.
(9)/(14)=(3)/(n)

9n = 42

n =
(42)/(9)

n =
(14)/(3)

15.
(b+13)/(2)=(-5b)/(3)

3b +39 = -10b

13b = -39

b = -3

16.
(3b)/(b-4)=(3)/(7)

21b = 3b - 12

21b - 3b = -12

18b = -12

b = -
(12)/(18)

b =
-(2)/(3)

17.
(x+2)/(2x-6)=(3)/(8)

8x + 16 = 6x - 18

8x - 6x = -18 - 16

2x = -34

x = -17
