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

We know that

1 liter> 1000 ml
Jennifer punch is 5 liters> 5*1000=5000 ml
Her brother punch> 750 ml
[total two batches]=(5000+750)> 5750 ml

the answer part A) is 5750 ml

Part B) how many 180 mL servings would they have?
[180 mL servings]=5750/180=31.94> 31 

they would have 31 (180 ml servings)
punch left over=[5750-31*180]=170 ml
there would  be 170 ml of punch left over

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
