MO MAP Grades 6-8 Ratios and Proportional Relationships Practice

What the test measures

Ratios and Proportional Relationships skills

Grade 6: ratio concepts, unit rates, ratio language
Grade 7: proportional relationships, scale drawings, percent problems
Grade 8: indirect support through proportional and linear relationship connections

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

An herbicide spray uses concentrate and water in a ratio of $6$ to $24$ . How many cups of concentrate should be added to $2$ quarts of water to make the spray in this ratio? ( $4$ cups $=$ $1$ quart, $4$ quarts $=$ $1$ gallon.)

Two quarts of water is $2 \times 4 = 8$ cups. With a $6$ to $24$ ratio, $\dfrac{6}{24} = \dfrac{x}{8}$ , so $24x = 48$ and $x = 2$ cups of concentrate.

A recipe uses $3$ cups of flour to make $18$ muffins. At this rate, how many cups of flour are needed to make $30$ muffins?

Set up a proportion: $\dfrac{3}{18} = \dfrac{x}{30}$ , so $18x = 90$ and $x = 5$ cups.

$x$ and $y$ are in the ratio $8$ to $3$ . Given that $y = 45$ , what is $x$ ?

$\dfrac{x}{y} = \dfrac{8}{3}$ . With $y = 45$ , $\dfrac{x}{45} = \dfrac{8}{3}$ , so $3x = 360$ and $x = 120$ .

What is $30\%$ of $90$ ?

Convert: $30\% = 0.3$ . Then $0.3 \times 90 = 27$ .

After a $25\%$ discount, a board game costs $\text{\char36}45$ . What was the original price, in dollars, before the discount?

The sale price is $75\%$ of the original: $0.75p = 45$ , so $p = 45 \div 0.75 = 60$ dollars.

Find the simple interest on $\text{\char36}100$ at $10\%$ per year for $1$ year.

$I = 100 \times 0.1 \times 1 = \$10$ .

The table shows miles driven and gasoline used over two weeks. At the same miles-per-gallon rate, how many gallons are needed to drive $150$ miles?
$\begin{array}{l|c|c} \text{Week} & \text{Miles} & \text{Gallons} \\ \hline 1 & 240 & 8 \\ 2 & 180 & 6 \end{array}$
