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
To find the percentage of milk left in the jug, we need to calculate the amount of milk poured out of the jug and subtract it from the initial amount of milk. Then we can calculate the percentage.
First, let's calculate the total amount of milk poured out of the jug:
221ml + 130ml = 351ml
Now, let's calculate the amount of milk left in the jug:
780ml - 351ml = 429ml
To find the percentage of milk left in the jug, we divide the amount of milk left by the initial amount of milk and multiply by 100:
(429ml / 780ml) * 100 = 55%
Therefore, the percentage of milk left in the jug is 55%.
To determine the percentage of milk left in the jug, you need to follow these steps:
1. Start by finding the total amount of milk poured out of the jug. Mrs. Li poured 221ml into a glass and 130ml into a cup, so the total amount is 221ml + 130ml = 351ml.
2. Subtract the total amount of milk poured out from the initial amount of milk in the jug. 780ml - 351ml = 429ml.
3. Now, you have the remaining amount of milk in the jug, which is 429ml.
4. To find the percentage, divide the remaining amount (429ml) by the initial amount (780ml), and then multiply by 100.
Percentage = (remaining amount / initial amount) x 100
= (429ml / 780ml) x 100
≈ 55.0%
Therefore, approximately 55.0% of the milk is left in the jug.
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 = ?
