1

Find the value of x in the proportion

21: 6 = 42:12

step 1

Write the given ratios in fraction form

21:y =

21y

42:12 =

4212

step 2

Find the Means & Extremes

21 x 12 = 42 x y

Extremes = 21, 12

Means = 42, y

21y

=

4212

Extremes = 21, 12

Means = 42, y

step 3

Rearrange the statement to find y

y = 6

y =

21 x 1242

step 4

The missing term in the proportion is 6

Therefore the proportion is 21: 6 = 42:12

Therefore the proportion is 21: 6 = 42:12

2

Find the value of x in the proportion

16:23 = 128:184

step 1

Write the given ratios in fraction form

16:23 =

1623

128:y =

128y

step 2

Find the Means & Extremes

16 x y = 128 x 23

Extremes = 16, y

Means = 128, 23

1623

=

128y

Extremes = 16, y

Means = 128, 23

step 3

Rearrange the statement to find y

y = 184

y =

128 x 2316

step 4

The missing term in the proportion is 184

Therefore the proportion is 16:23 = 128:184

Therefore the proportion is 16:23 = 128:184

3

Find the value of x in the proportion

5: 6 = 45:54

step 1

Write the given ratios in fraction form

5:y =

5y

45:54 =

4554

step 2

Find the Means & Extremes

5 x 54 = 45 x y

Extremes = 5, 54

Means = 45, y

5y

=

4554

Extremes = 5, 54

Means = 45, y

step 3

Rearrange the statement to find y

y = 6

y =

5 x 5445

step 4

The missing term in the proportion is 6

Therefore the proportion is 5: 6 = 45:54

Therefore the proportion is 5: 6 = 45:54

4

Find the value of x in the proportion

20:11 = 120:66

step 1

Write the given ratios in fraction form

y:11 =

y11

120:66 =

12066

step 2

Find the Means & Extremes

x 66 = 120 x 11

Extremes = 66, y

Means = 120, 11

y11

=

12066

Extremes = 66, y

Means = 120, 11

step 3

Rearrange the statement to find y

y = 20

y =

120 x 1166

step 4

The missing term in the proportion is 20

Therefore the proportion is 20:11 = 120:66

Therefore the proportion is 20:11 = 120:66

5

Find the value of x in the proportion

2:7 = 10:35

step 1

Write the given ratios in fraction form

y:7 =

y7

10:35 =

1035

step 2

Find the Means & Extremes

x 35 = 10 x 7

Extremes = 35, y

Means = 10, 7

y7

=

1035

Extremes = 35, y

Means = 10, 7

step 3

Rearrange the statement to find y

y = 2

y =

10 x 735

step 4

The missing term in the proportion is 2

Therefore the proportion is 2:7 = 10:35

Therefore the proportion is 2:7 = 10:35

6

Find the value of x in the proportion

25:13 = 225:117

step 1

Write the given ratios in fraction form

25:13 =

2513

225:y =

225y

step 2

Find the Means & Extremes

25 x y = 225 x 13

Extremes = 25, y

Means = 225, 13

2513

=

225y

Extremes = 25, y

Means = 225, 13

step 3

Rearrange the statement to find y

y = 117

y =

225 x 1325

step 4

The missing term in the proportion is 117

Therefore the proportion is 25:13 = 225:117

Therefore the proportion is 25:13 = 225:117

7

Find the value of x in the proportion

3:22 = 24:176

step 1

Write the given ratios in fraction form

3:22 =

322

24:y =

24y

step 2

Find the Means & Extremes

3 x y = 24 x 22

Extremes = 3, y

Means = 24, 22

322

=

24y

Extremes = 3, y

Means = 24, 22

step 3

Rearrange the statement to find y

y = 176

y =

24 x 223

step 4

The missing term in the proportion is 176

Therefore the proportion is 3:22 = 24:176

Therefore the proportion is 3:22 = 24:176

8

step 1

Write the given ratios in fraction form

7:24 =

724

y:24 =

y48

step 2

Find the Means & Extremes

7 x 48 = y x 24

Extremes = 7, 48

Means = 24, y

724

=

y48

Extremes = 7, 48

Means = 24, y

step 3

Rearrange the statement to find y

y = 14

y =

7 x 4824

step 4

The missing term in the proportion is 14

Therefore the proportion is 7:24 = 14:48

Therefore the proportion is 7:24 = 14:48

9

Find the value of x in the proportion

16:5 = 48:15

step 1

Write the given ratios in fraction form

16:5 =

165

48:y =

48y

step 2

Find the Means & Extremes

16 x y = 48 x 5

Extremes = 16, y

Means = 48, 5

165

=

48y

Extremes = 16, y

Means = 48, 5

step 3

Rearrange the statement to find y

y = 15

y =

48 x 516

step 4

The missing term in the proportion is 15

Therefore the proportion is 16:5 = 48:15

Therefore the proportion is 16:5 = 48:15

10

2:7 = 18:63

step 1

Write the given ratios in fraction form

2:7 =

27

y:7 =

y63

step 2

Find the Means & Extremes

2 x 63 = y x 7
