To make the ratios proportional, we need to find a denominator for 21 thirds that, when added to the numerator of 49, would result in an equivalent fraction.
To find this denominator, we can set up the following equation:
21/3 = 49/x
Cross-multiplying, we get:
21x = 147
Dividing both sides by 21, we find that x = 7
Therefore, the denominator needed for the fraction 21 thirds to make the ratios proportional would be 49/7.
What denominator for 21 thirds = 49/ ? would make these ratios proportional?
