Question

these form a proportion: 10 altos for every 16 sopranos, 5 altos for every 8 sopranos. True or False?

Answer 1

True

Step-by-step explanation:

A proportion states the equality of two fractions. It is an equation that shows that two fractions are equivalent to each other.

Looking at the given statement;

10 altos for every 16 sopranos, 5 altos for every 8 sopranos.

This can be expressed as;

`(10)/(16),(5)/(8)`

And we can see that the two fractions are equivalent, if we divide the numerator and denominator of the 1st fraction by 2 we'll have the 2nd fraction.
