1. A tank contains 250 litres or weathe
kaheart [24]

Answer:

61.6%

Step-by-step explanation:

We know that the tank contains 250 litres and that 96 litres are used. We are trying to find the percentage of the leftover quantity.

First, we need to subtract 250 from 96 litres to get the quantity that is left in the tank in litres. 250-96=154.

Then we need to find the percentage. To find a percentage we need to divide the total minus and the used amount by the total amount and then multiple the whole thing by 100. So in our case, that would be 250-96=154/250*100. Or 154/250*100.

Thus the answer is 61.6%.
