A jug contained 780ml of milk.Mrs Li poured 221ml of the milk into a glass and 130ml into a cup.what percentage of milk was left in the jug?pls give ur answer clearly
Start with 780 mL milk.
Placed 221 mL in glass + 130 mL in cup = 351 mL removed from the jug.
How much is left in the jug? That will be 780 mL - 351 mL = 429
% remaining = (429/780)*100 = ?
