Question

An ice cream parlor makes 1/3 of it's income from cones and 40% from sundaes. What fraction of it's income comes from other items

Answer 1

4/15

Explanation:

40% = 2/5 = 6/15

1/3 = 5/15

15/15 - 6/15 - 5/15 = 4/15

4/15 of its income comes from other items.

Answer 2

If we turn 40% into a fraction to match the 1/3, we have 4/10(2/5 in simplest form) and 1/3. Now we have to make them both the same so multiply 1/3 by 5 giving 5/15 and multiply 2/5 by 3 to get 6/15. Add these two fractions together and you get 11/15. Meaning 4/15 of income comes from other items
