To determine the denominator that would make the ratios proportional, we need to find the missing value in the second ratio when the first ratio is 21/3 = 7.
We can set up a proportion:
21/3 = 49/x
To find x, we can cross multiply:
21 * x = 3 * 49
21x = 147
Dividing both sides by 21:
x = 7
Therefore, the denominator that would make the ratios proportional is 7, so 21/3 = 49/7.
What denominator for 21/3 = 49/? would make these ratios proportional?

Apologies for the mistake.
To find the denominator that would make the ratios proportional, we can set up a proportion using the given ratios:
21/3 = 49/x
Cross multiplying, we have:
21x = 3 * 49
Dividing both sides by 3:
x = (3 * 49)/21
Reducing the fraction:
x = (3 * 7 * 7)/21
Canceling out common factors:
x = 1 * 7
Therefore, the denominator that would make the ratios proportional is 7. Hence, 21/3 = 49/7.

still wrong
Apologies for the incorrect response.
To find the denominator that would make the ratios proportional, we can set up a proportion using the given ratios:
21/3 = 49/x
For two ratios to be proportional, the cross products must be equal. Cross multiplying, we have:
21x = 3 * 49
To solve for x, we need to divide both sides by 21:
x = (3 * 49) / 21
Simplifying the expression:
x = 7 * 7 / 3
In order to find the denominator that would make the ratios proportional, we need to choose a value for x that results in a whole number. The smallest value that works is when x = 7.
Therefore, the denominator that would make the ratios proportional is 7. The new ratio is 21/3 = 49/7.
