Question
If the equivalent ratio of y:19 is 56:133, the value of y is _____________.
- 60
- 50
- 7
- 8
Hint:
Equivalent ratios are those that can be simplified or reduced to the same value. In other words, two ratios are considered equivalent if one can be expressed as a multiple of the other.
The correct answer is: 8
Here, we have to find the value of y such that the ratios y:19 and 56:133 are equivalent.
For y:19 and 56:133 to be equivalent, we must have
y⁄19 = 56⁄133
=> y = (56×19)⁄133
=> y = 8.
Hence, the correct option is D.
