Answer: 3 : 5 and 6 : 10
Explanation: First rewrite the ratio 12 : 20 as the fraction 12/20.
Next, we can find an equal ratio by
simply writing this fraction in lowest terms.
If we divide both the numerator and denominator of 12/20
by their greatest common factor of 4, we get the equal ratio 3/5.
Now we can use 3/5 to find another equal ratio.
If we multiply both the numerator and denominator
of 3/5 by 2, we get the equal ratio 6/10.
So 12 : 20 is equal to 3 : 5 and 6 : 10.
