Hello!
Let's convert 3/4 to a decimal, and then subtract that from the whole so that we know how much pizza is left.
To convert a fraction to a decimal, we must divide the numerator by the denominator.
3 ÷ 4 = 0.75
One whole would be 1.
1 - 0.75 = 0.25
That is the remaining amount of pizza. Now, we must split this into two for the daughter and the son. To do this, we will use the operation called division.
0.25 ÷ 2 = 0.125
A N S W E R:
They will recieve 0.125 pizza each.
