Question

Is 3/7 and 10/21 proportional ? 15 points

Answer 1

Answer:

NOT proportional.

Step-by-step explanation:

Get a common denominator of 21 by multiplying 7 and 3 by 3.

$\frac{3}{7}(\frac{3}{3})=\frac{9}{21}$

When both fractions have the same denominator, their numerators are different. Therefore, they are NOT proportional.
