6th Grade Ratio Tables and Graphs of Ratios Quiz: 10 Questions with Explanations

A 18B 12C 14D 9

The ratio is 1 to 3, so \(6 \times 3 = 18\). The value 12 just repeats the previous y instead of scaling.

A (6, 15)B (6, 12)C (4, 12)D (5, 8)

For 2 to 5, y = 2.5 x. For x = 6, y = 15.

A 18B 19C 20D 24

The ratio is 3 to 4. \(15 \div 3 = 5\) and \(4 \times 5 = 20\).

A The points lie on a straight line through the originB The points form a curveC The points are all in a vertical lineD The line stops at (1, 2)

Equivalent ratios plot as points on a line through (0, 0).

A 9 milesB 8 milesC 15 milesD 5 miles

24 minutes is 8 minutes per mile. \(40 \div 8 = 5\) miles.

A 6 to 14B 9 to 20C 9 to 21D 12 to 28

3 to 7 scaled by 3 is 9 to 21, not 9 to 20.

A $36B $45C $40D $90

\(\$18 \div 2 = \$9\) per hour, and \(5 \times \$9 = \$45\).

A 20 applesB 12 applesC 50 applesD 25 apples

\(10 \div 2 = 5\) groups, and \(5 \times 5 = 25\) apples.

A Line A rises fasterB Line B rises fasterC They rise at the same rateD Neither goes through the origin

B increases by 4 for each 1 across, and A by 3.

A 4, 8, 12 and 5, 9, 13B 4, 8, 12 and 9, 13, 17C 4, 8, 12 and 5, 10, 15D 4, 8, 12 and 5, 10, 14

Both numbers are multiplied by the same factor: 1, 2, 3.
