Answer
The choir director would want 15 altos if there are 21 sopranos.
Solution
The ratio of altos to sopranos is 5:7. This means for every 7 sopranos, there are 5 altos. With 21 sopranos, we notice that 21 divided by 7 is 3. Therefore, the number of altos is 5 × 3 = 15.

If there are 21 sopranos, we can set up a proportion based on the desired ratio of altos to sopranos. Since the ratio is 5 altos for every 7 sopranos, we can establish the relationship: 5/7 = x/21, where x represents the number of altos. Cross-multiplying gives us 5 * 21 = 7 * x. This simplifies to 105 = 7x, which leads to x = 15. Therefore, the choir director would want 15 altos to maintain the right balance with 21 sopranos!
