Grade 6 · Common Core State Standards: 6.RP.A.1

Ratios practice solutions: exercises 1 to 10

Exercise 1 – Write a ratio

There are 3 red tiles and 5 blue tiles.

The ratio of red to blue is \(3:5\), or 3 to 5, or \(\frac{3}{5}\).

\(3:5\)

Exercise 2 – Three ways to write it

Cats come first, dogs second.

\(4:7\), 4 to 7, \(\frac{4}{7}\)

\(4:7\)

Exercise 3 – Part to whole

Part to whole: boys to all students.

The ratio is \(5:12\).

\(5:12\)

Exercise 4 – Order matters

(a) Girls to boys: \(9:6\).

(b) Boys to girls: \(6:9\).

The order of the numbers follows the order of the words.

(a) \(9:6\); (b) \(6:9\)

Exercise 5 – Simplify a ratio

The greatest common factor of 12 and 18 is 6.

\(12 \div 6 = 2\) and \(18 \div 6 = 3\).

\(2:3\)

Exercise 6 – Complete the equivalent ratio

\(3 \times 3 = 9\), so multiply 4 by 3 as well.

\(4 \times 3 = 12\)

\(9:12\)

Exercise 7 – Fruit bowl

Total fruit: \(8 + 5 = 13\).

Apples to all fruit: \(8:13\).

\(8:13\)

Exercise 8 – Basketball shots

Made to missed is \(9:6\).

Divide both numbers by 3: \(3:2\).

\(3:2\)

Exercise 9 – Simplify with larger numbers

The greatest common factor is 12.

\(24 \div 12 = 2\), \(36 \div 12 = 3\).

\(2:3\)

Exercise 10 – Same units

1 hour = 60 minutes, so the ratio is \(45:60\).

Divide both by 15: \(3:4\).

\(3:4\)

Exercises 11 and up

Exercise 11 – Three equivalent ratios

Multiply both numbers by the same number.

\(3 \times 2 : 7 \times 2 = 6:14\), \(3 \times 3 : 7 \times 3 = 9:21\), \(3 \times 4 : 7 \times 4 = 12:28\).

\(6:14\), \(9:21\), \(12:28\)

Exercise 12 – Shapes in a quilt

The ratio is \(6:9\).

Divide both by 3.

\(2:3\)

Exercise 13 – Are they equivalent?

\(6:9\) simplifies to \(2:3\) (divide by 3).

\(8:12\) simplifies to \(2:3\) (divide by 4).

Both simplify to \(2:3\).

Yes, they are equivalent.

Exercise 14 – Not equivalent

\(4:6\) simplifies to \(2:3\).

\(6:10\) simplifies to \(3:5\).

\(2:3\) is not \(3:5\).

No, they are not equivalent.

Exercise 15 – Trail mix

\(12 \div 3 = 4\), so the recipe is made 4 times.

\(2 \times 4 = 8\)

8 cups of raisins

Exercise 16 – Mixing paint

\(15 \div 5 = 3\), so there are 3 batches.

\(3 \times 3 = 9\)

9 cups of red paint

Three batches: 15 cups of white goes with 9 cups of red.

Exercise 17 – Little League record

Each group has \(3 + 2 = 5\) games.

\(20 \div 5 = 4\) groups.

Wins: \(3 \times 4 = 12\).

12 wins

Four groups of 3 wins and 2 losses make 20 games.

Exercise 18 – Class ratio

Each group has \(4 + 5 = 9\) students.

\(27 \div 9 = 3\) groups.

Boys: \(4 \times 3 = 12\). Girls: \(5 \times 3 = 15\).

Check: \(12 + 15 = 27\).

12 boys and 15 girls

27 students in 9 groups of 3.

Exercise 19 – Farmers market

Each group has \(5 + 3 = 8\) pieces.

\(64 \div 8 = 8\) groups.

Apples: \(5 \times 8 = 40\). Pears: \(3 \times 8 = 24\).

40 apples and 24 pears

Exercise 20 – Which lemonade is stronger?

A: lemon to water is \(3:6\) = \(1:2\). That is 1 cup of lemon juice for every 2 cups of water.

B: \(4:12\) = \(1:3\). That is 1 cup of lemon juice for every 3 cups of water.

A has more lemon juice for the same amount of water.

Lemonade A is stronger.
