We will see that 20 children can get a serving.
To see how many children can get a serving we need to take the quotient between the total amount of grapes and the amount of grapes needed for each serving.
We know that there are 5 bunches of grapes, and each serving needs 1/4 bunches, then we need to solve:
[tex]\frac{5}{1/4}[/tex]
Notice that we can write 5 as a fraction:
5 = 5/1
then:
[tex]\frac{5/1}{1/4}[/tex]
Now, the two numbers in the middle (both ones) remain on the denominator, while the other 2 conform the numerator, then we have:
[tex]\frac{5/1}{1/4} = \frac{5*4}{1*1} = 20[/tex]
So 20 children can get a serving.
