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.
