Question

What denominator for 21/3=49/? would make these ratios proportional?(1 point)

Answer 1

To make the ratios proportional, the denominator for 21/3 should be the same as the denominator for 49/?.

Let's use x as the denominator for 21/3 and y as the denominator for 49/?.

Therefore, we have the equation:

21/x = 49/y

We need to find the value of y that makes this equation true.

To solve for y, we can cross-multiply:

21y = 49x

Now we can solve for y by dividing both sides of the equation by 49:

y = (49x)/21

Therefore, the denominator for 21/3 that would make the ratios proportional is 21.
