1

Find the value of x in the proportion

21:6 = 42:12

step 1

Write the given ratios in fraction form

y:6 =

y6

42:12 =

4212

step 2

Find the Means & Extremes

x 12 = 42 x 6

Extremes = 12, y

Means = 42, 6

y6

=

4212

Extremes = 12, y

Means = 42, 6

step 3

Rearrange the statement to find y

y = 21

y =

42 x 612

step 4

The missing term in the proportion is 21

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:y =

16y

128:184 =

128184

step 2

Find the Means & Extremes

16 x 184 = 128 x y

Extremes = 16, 184

Means = 128, y

16y

=

128184

Extremes = 16, 184

Means = 128, y

step 3

Rearrange the statement to find y

y = 23

y =

16 x 184128

step 4

The missing term in the proportion is 23

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

20:11 =

2011

y:11 =

y66

step 2

Find the Means & Extremes

20 x 66 = y x 11

Extremes = 20, 66

Means = 11, y

2011

=

y66

Extremes = 20, 66

Means = 11, y

step 3

Rearrange the statement to find y

y = 120

y =

20 x 6611

step 4

The missing term in the proportion is 120

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:y =

25y

225:117 =

225117

step 2

Find the Means & Extremes

25 x 117 = 225 x y

Extremes = 25, 117

Means = 225, y

25y

=

225117

Extremes = 25, 117

Means = 225, y

step 3

Rearrange the statement to find y

y = 13

y =

25 x 117225

step 4

The missing term in the proportion is 13

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

y:22 =

y176

step 2

Find the Means & Extremes

3 x 176 = y x 22

Extremes = 3, 176

Means = 22, y

322

=

y176

Extremes = 3, 176

Means = 22, y

step 3

Rearrange the statement to find y

y = 24

y =

3 x 17622

step 4

The missing term in the proportion is 24

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

y:5 =

y15

step 2

Find the Means & Extremes

16 x 15 = y x 5

Extremes = 16, 15

Means = 5, y

165

=

y15

Extremes = 16, 15

Means = 5, y

step 3

Rearrange the statement to find y

y = 48

y =

16 x 155

step 4

The missing term in the proportion is 48

Therefore the proportion is 16:5 = 48:15

Therefore the proportion is 16:5 = 48:15

10

Find the value of x in the proportion

2: 7 = 18:63

step 1

Write the given ratios in fraction form

2:y =

2y

18:63 =

1863

step 2

Find the Means & Extremes

2 x 63 = 18 x y

Extremes = 2, 63

Means = 18, y

2y

=

1863

Extremes = 2, 63

Means = 18, y

step 3

Rearrange the statement to find y

y = 7

y =

2 x 6318
