Answer 3

To subtract mixed numbers, we need to find a common denominator for the fractions involved. In this case, the common denominator is 15. Let's calculate the subtraction:

7 and 5/15 - 4 and 8/15

First, let's convert the mixed numbers into improper fractions:

7 and 5/15 = (7 * 15 + 5)/15 = 110/15 4 and 8/15 = (4 * 15 + 8)/15 = 68/15

Now we can subtract the fractions:

110/15 - 68/15 = (110 - 68)/15 = 42/15

The resulting fraction is 42/15. However, we can simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 3:

42/15 = (42 ÷ 3)/(15 ÷ 3) = 14/5

Therefore, 7 and 5/15 minus 4 and 8/15 equals 14/5 or 2 and 4/5.
