Question

The average adult has approximately 1.25 gallons of blood. Blood donors typically donate 1 pint of blood. How many donations would it take until someone donated all of his or her blood? Even though that's not possible! Hint: refer to the conversion graphic right to determine how many pints there are in 1 gallon.

Answer 1

10 pints.
We know that there are 8 pints in a gallon. We have one gallon so we already have 8 pints.
Then there is a .25 gallon, this is equivalent to one-fourth of a gallon. So 1/4 times 8 is 2.
8 + 2 is 10 pints.

Answer 2

10 pints is the answer
