Scaling ratios
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- first term missing: 2 : 3 = x : 9
- second term missing: 2 : 3 = 6 : x
Sample Sheet · Level 1
- 4 : 3 = x : 9
- 6 : 3 = 18 : x
- 5 : 6 = x : 12
- 5 : 1 = 10 : x
- 3 : 1 = x : 2
- 6 : 2 = 24 : x
- 5 : 2 = x : 8
- 1 : 6 = 4 : x
Answer key
- x = 12
- x = 9
- x = 10
- x = 2
- x = 6
- x = 8
- x = 20
- x = 24
Sample Sheet · Level 3
- 9 : 3 = 36 : x
- 7 : x = 42 : 66
- x : 8 = 42 : 48
- x : 7 = 50 : 35
- 1 : x = 2 : 4
- x : 11 = 63 : 77
- x : 10 = 24 : 80
- 7 : 2 = 28 : x
Answer key
- x = 12
- x = 11
- x = 7
- x = 10
- x = 2
- x = 9
- x = 3
- x = 8
