## McGraw-Hill My Math Grade 3 Answer Key Chapter 10 Lesson 6 Equivalent Fractions

Fractions that name the same part of the whole are equivalent fractions. Equivalent fractions are equal and have the same size.

**Math in My World**

**Example 1**

Noah has one half of a fruit pizza. How could Noah cut the pizza into smaller equal-sized pieces and still have half of the whole pizza?

1. Use \(\frac{1}{4}\)-fraction tiles to equal the length of the \(\frac{1}{2}\)-fraction tile model.

How many \(\frac{1}{4}\)-tiles are there? ______________

So, \(\frac{1}{2}\) = \(\frac{2}{4}\). They are ____________ fractions. They represent the same part of one whole.

Answer:

\(\frac{1}{4}\)-fraction tiles to equal the length of the \(\frac{1}{2}\)-fraction tile model.

There are 2 \(\frac{1}{4}\)-fraction tiles that is equal to the length of \(\frac{1}{2}\)-fraction tile model.

2. Noah could cut half of the pizza into even smaller equal-sized pieces.

Use \(\frac{1}{8}\)-fraction tiles to equal the length of the \(\frac{1}{2}\)-fraction tile model.

How many \(\frac{1}{8}\)-tiles are there?

So, \(\frac{1}{2}\) = \(\frac{2}{4}\) = \(\frac{4}{8}\). They are ____________ fractions.

Half of the fruit pizza is the same as \(\frac{2}{4}\) or \(\frac{4}{8}\) of the pizza.

Answer:

\(\frac{1}{2}\) = \(\frac{2}{4}\) = \(\frac{4}{8}\).

There are 4 fractions.

**Example 2**

Kwan’s bookshelf has 3 shelves. Only one of the shelves has books. Kwan says \(\frac{1}{3}\) of the shelves have books. His mom says \(\frac{2}{6}\) of the shelves have books. Are they both correct?

Use fraction tiles and number lines to find if the fractions are equivalent.

One Way:

Use fraction tiles.

One-third of one whole is equivalent to \(\frac{2}{6}\).

Another Way:

Use number lines.

One-third of one whole shares the same point on the number line as \(\frac{2}{6}\).

They are both correct. \(\frac{1}{3}\) = \(\frac{2}{6}\) so, they are ______________ fractions.

Answer:

Kwan’s bookshelf has 3 shelves. Only one of the shelves has books. Kwan says \(\frac{1}{3}\) of the shelves have books. His mom says \(\frac{2}{6}\) of the shelves have books.

\(\frac{2}{6}\) = \(\frac{1}{3}\)

So, yes they are both correct.

There are two fractions.
