What is three ratios equivalent to 18:4
36:8, 9:2, and 72: 16 would all be equivalent.
In order to find ratios that are equivalent to 18:4, you have to multiply both numbers by the same factor.
For instance, when we use a factor of two and multiply it by each term, we get 36:8 because 182=36 and 42 = 8.
The second and third options above are for when the numbers are multiplied by 1/2 and 4 respectively.
For this case we have the following ratio:
\(\frac{18}{4}\)
What we must do is write three equivalent ratios.
For this, we must rewrite the fraction.
We have then:
Way 1:
Divide numerator and denominator between two:
\(\frac{\frac{18}{2}}{\frac{4}{2}} = \frac{9}{2}\)
Way 2:
Multiply numerator and denominator by two:
\(\frac{18}{4} \frac{2}{2} =\frac{36}{8}\)
Way 3:
Multiply numerator and denominator by four:
\(\frac{18}{4}\frac{4}{4} =\frac{72}{16}\)
