Which of the following numbers can replace the missing numerator to make the addition sentence true? 32/57 + ?57 = 54/57
To make the addition sentence true, we need to find the missing numerator such that when added to 32/57, it equals 54/57.
We can use the fact that the denominators are the same (57) and set up the equation:
32/57 + x/57 = 54/57
To solve for x, we can subtract 32/57 from both sides:
x/57 = 54/57 - 32/57
Subtracting the fractions on the right side gives:
x/57 = 22/57
Now, to isolate x, we can multiply both sides by 57:
57 * (x/57) = 57 * (22/57)
The 57s on the left side of the equation cancel out, and we are left with:
x = 22
Therefore, the missing numerator that can replace the "?" is 22.
