5. (a) Individual cereal boxes contain 4 2/3 ounces of cereal. There is a supply of 81 ounces of cereal.(i) How many full boxes of cereal can be made?(ii) How many ounces of cereal will be left over?(Give an exact answer in ounces using a common fraction or a mixed number in simplest form).

Respuesta :

so each cereal box has 4 2/3 ounces of cereal, or 14/3 ounces (just changing the integer to fraction)

for a), we have to divide 81 by 14/3 like this:

[tex]81\text{ / (14/3) = 243/14}[/tex]

in decimals, 243/14 = 17.35

so, for a), we have that 17 full boxes of cereal can be made

for b), you have to look at the decimals of the last division

We have that .35 of cereal was left out, which is the same as 35/100 or 7/20
