1.375 pounds

Step-by-step explanation:

We want to find how many pounds of candy he has left.

He bought 5 pounds.

He gave out 3 pounds.

He ate 10 ounces. Converting 10 ounces to pounds:

1 ounce = 0.0625 pounds

10 ounces = 10 * 0.0625 = 0.625 pounds

Therefore the amount of candy he has left is:

5 - (3 + 0.625)

= 5 - (3.625)

= 1.375 pounds

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
