Identify the missing numerator in the addition expression 13/24 + ?/24 = 19/24.
To identify the missing numerator in the addition expression, we can subtract the known numerator from the sum of the fractions on the right side of the equation.
The known numerator is 13/24, the sum of the fractions on the right side is 19/24, so the missing numerator can be found by subtracting 13/24 from 19/24.
(19/24) - (13/24) = 6/24
Therefore, the missing numerator in the addition expression is 6.
