Question
Don wants to resize the window of his house. If the ratio of length and breadth is 4:8. The new ratio formed after the size is increased by 4 times will be __________.
- 16:32
- 20:25
- 32:16
- 16:18
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: 16:32
Here, it is given that the ratio of length and breadth of a window is 4:8 which is to be increased in size by a factor of 4. We have to find the new ratio.
We have, ratio =4:8
Then, new ratio = (4×4): (8×4) = 16:32.
Hence, the correct option is A.
The value of the ratio remains the same whether it is increased or decreased by some factor.
