Jennifer made 5l of punch for her party. her brother made another 750 ml. if the combined the two batches, how many 180 ml servings would they have? would there be any punch left over? if so how much.

First is solve the total volume of punch they made. but convert first the 5 L to ml.

for every 1 L there 1000 ml, 5 L (1000 ml / 1 L) = 5000 ml of punch

V = 5000 ml + 750 ml

V = 5750 ml

then number of 180 ml serving

n = 5750 / 180 = 31.94 or about 31 servings of 180 ml was made.

the punch left over

v = 5750 - 180 (31) = 170 ml of the punch is left
