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

16:23 =

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

y:6 =

y6

45:54 =

4554

step 2

Find the Means & Extremes

x 54 = 45 x 6

Extremes = 54, y

Means = 45, 6

y6

=

4554

Extremes = 54, y

Means = 45, 6

step 3

Rearrange the statement to find y

y = 5

y =

45 x 654

step 4

The missing term in the proportion is 5

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

2:7 =

27

y:7 =

y35

step 2

Find the Means & Extremes

2 x 35 = y x 7

Extremes = 2, 35

Means = 7, y

27

=

y35

Extremes = 2, 35

Means = 7, y

step 3

Rearrange the statement to find y

y = 10

y =

2 x 357

step 4

The missing term in the proportion is 10

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

7: 24 = 14:48

step 1

Write the given ratios in fraction form

7:y =

7y

14:48 =

1448

step 2

Find the Means & Extremes

7 x 48 = 14 x y

Extremes = 7, 48

Means = 14, y

7y

=

1448

Extremes = 7, 48

Means = 14, y

step 3

Rearrange the statement to find y

y = 24

y =

7 x 4814

step 4

The missing term in the proportion is 24

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

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
