Explanation: First rewrite the ratio 3 : 12 as the fraction 3/12.
Next, we can find an equal ratio by
simply writing this fraction in lowest terms.
If we divide both the numerator and the denominator of 3/12
by their greatest common factor of 3, we get the equal ratio 1/4.
Now we can use 1/4 to find another equal ratio.
If we multiply both the numerator and denominator
of 1/4 by 2, we get the equal ratio 2/8.
So 3 : 12 is equal to 1 : 4 and 2 : 8.
Make sure to write your final answers as the same
form in the original problem.
