an adult has about 5 quarts of blood. when he donates a pint for a sick friend, what fraction of his blood does he give away
how many pints are in 5 quarts?
LOOK IT UP
To find the fraction of blood an adult gives away when donating a pint, we need to convert the units of measurement to match.
There are 2 pints in a quart, so if an adult has 5 quarts of blood, they have 5 x 2 = 10 pints of blood.
When donating a pint, they give away 1 pint, so the fraction of blood given away can be calculated as 1/10.
Therefore, an adult gives away 1/10th or 1/10 fraction of their blood when donating a pint.
