Julia has a total of 21 shirts in her dresser.if 3 of the shirts are blue what is the ratio of blue shirts to nonblue shirts in her dresser

Respuesta :

The ratio  is 1:6.

Explanation:

If you subtract 3 from 21, you get 18. Now the ratio is equal to 3:18 (blue to non-blue). Now if we simplify (find the least common factor, or LCF), the least common factor is 3. So if were to divide both numbers by 3, we get 1:6.

Hope I helped, and good luck!
