Question 1

A gardener planted 28 bushes in 4 rows. All of the bushes were either rose bushes or lilac bushes. The shaded parts of the model represent the lilac bushes.

Which equation shows how to find the fraction of the bushes that are lilac bushes?

Accepted Answer

$$\frac{4}{28}+\frac{3}{28}+\frac{3}{28}+\frac{5}{28}=\frac{15}{28}$$

Answer

$$\frac{3}{28}+\frac{4}{28}+\frac{4}{28}+\frac{2}{28}=\frac{13}{28}$$

Answer

$$\frac{4}{7}+\frac{3}{7}+\frac{3}{7}+\frac{5}{7}=\frac{15}{28}$$

Answer

$$\frac{15}{28}+\frac{13}{28}=\frac{28}{28}$$

Question 2

Kendrick used $$4\ \frac{5}{8}$$ bags of dirt in a garden of roses and $$9\ \frac{1}{8}$$ bags of dirt in a garden of wildflowers.

Which equation can be used to find the number of bags of dirt Kenrick used?

Accepted Answer

$$4\ +\ 9\ +\ \frac{5}{8\ }\ +\ \frac{1}{8}\ =\ 13\ \frac{6}{8}$$

Answer

$$\frac{4}{8}+\frac{5}{8}+\frac{9}{8}+\frac{1}{8\ }=\frac{19}{8}$$

Answer

$$\frac{9}{8}+\frac{10}{8}\ =\frac{19}{16}$$

Answer

$$\frac{20}{8}+\frac{9}{8}=3\ \frac{5}{8}$$

Question 3

Ignacio and Elaine read the same book. The shaded part of each model represents the fraction of the book that each student read.

Which expression can be used to find the difference between the fraction of the book Elaine read and the fraction of the book Ignacio read?

Accepted Answer

$$\frac{16}{20}-\frac{13}{20}$$

Answer
