Using the given model, find
five-eighths subtract one-quarter. Give your answer in its simplest
form.
In this question, we have to find
five-eighths subtract one-quarter, and we’ve been given a model to help. The first model represents
five-eighths. The whole amount has been divided
into eight equal parts, and five of those eight parts have been shaded. We have to subtract one-quarter
from these five-eighths. Our second model represents
one-quarter. The whole amount has been divided
into four equal parts, and one of those four parts has been shaded.
By comparing these two models, we
can see that one-quarter is equal to two-eighths. So to subtract a quarter from our
five-eighths, we need to take away two-eighths. One, two. How many eighths do we have
left? There are three. So five-eighths take away
one-quarter is equal to five-eighths take away two-eighths. So if we have five-eighths and we
take away two, we’ll have three-eighths left. And the question says we have to
give our answer in its simplest form. We can’t simplify
three-eighths. Five-eighths take away one-quarter
equals three-eighths.
