A restaurant ordered 6.6 pounds of pasta. The next night, the restaurant used 1.3 pounds of it. How much pasta is left?

The restaurant has 6.6 - 1.3 = 5.3 pounds of pasta left.

To find out how much pasta is left, we need to subtract the amount used from the original amount ordered.

Amount of pasta left = Amount ordered - Amount used.

Using the given values:

Amount ordered = 6.6 pounds
Amount used = 1.3 pounds.

Substituting these values into the formula, we have:

Amount of pasta left = 6.6 pounds - 1.3 pounds.

Calculating this, we get:

Amount of pasta left = 5.3 pounds.

Therefore, there is 5.3 pounds of pasta left.

To find out how much pasta is left, you need to subtract the amount of pasta used (1.3 pounds) from the initial amount of pasta ordered (6.6 pounds).

So, to get the answer, perform the subtraction:
6.6 pounds - 1.3 pounds = 5.3 pounds

Therefore, there are 5.3 pounds of pasta left.
