1

Find the value of x in the proportion

21:6 = 42:12

step 1

Write the given ratios in fraction form

21:6 =

216

y:6 =

y12

step 2

Find the Means & Extremes

21 x 12 = y x 6

Extremes = 21, 12

Means = 6, y

216

=

y12

Extremes = 21, 12

Means = 6, y

step 3

Rearrange the statement to find y

y = 42

y =

21 x 126

step 4

The missing term in the proportion is 42

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

120:y =

120y

step 2

Find the Means & Extremes

20 x y = 120 x 11

Extremes = 20, y

Means = 120, 11

2011

=

120y

Extremes = 20, y

Means = 120, 11

step 3

Rearrange the statement to find y

y = 66

y =

120 x 1120

step 4

The missing term in the proportion is 66

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

2:7 =

27

10:y =

10y

step 2

Find the Means & Extremes

2 x y = 10 x 7

Extremes = 2, y

Means = 10, 7

27

=

10y

Extremes = 2, y

Means = 10, 7

step 3

Rearrange the statement to find y

y = 35

y =

10 x 72

step 4

The missing term in the proportion is 35

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

y:22 =

y22

24:176 =

24176

step 2

Find the Means & Extremes

x 176 = 24 x 22

Extremes = 176, y

Means = 24, 22

y22

=

24176

Extremes = 176, y

Means = 24, 22

step 3

Rearrange the statement to find y

y = 3

y =

24 x 22176

step 4

The missing term in the proportion is 3

Therefore the proportion is 3:22 = 24:176

Therefore the proportion is 3:22 = 24:176

14:48 =

1448

step 2

Find the Means & Extremes

x 48 = 14 x 24

Extremes = 48, y

Means = 14, 24

y24

=

1448

Extremes = 48, y

Means = 14, 24

step 3

Rearrange the statement to find y

y = 7

y =

14 x 2448

step 4

The missing term in the proportion is 7

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

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
