Ratio Tables Quiz

Imagine James and Zoe are having a baking contest! They've decided to bake the most delicious cupcakes. The recipe they're following calls for 2 cups of flour for every 3 cups of sugar. If Zoe decides to go big and use 9 cups of sugar, how many cups of flour will she need to keep the recipe perfect?

• 4 cups

• 6 cups

• 12 cups

• 18 cups

Answer explanation

To find the cups of flour needed, set up a ratio: 2 cups of flour for every 3 cups of sugar. If 3 cups of sugar require 2 cups of flour, then 9 cups of sugar will need 6 cups of flour (9/3 * 2 = 6). Therefore, 6 cups of flour are needed.

In a lively classroom filled with eager students, Avery noticed that the ratio of boys to girls is quite balanced at 4:5. Being a curious mind, Avery counted and found there are 20 boys. Avery wonders, with a smile, how many girls are there sharing this vibrant learning space?

• 16

• 20

• 25

• 45

Answer explanation

To find the number of girls, multiply the number of boys by the ratio of girls to boys (5/4). So, 20 boys * (5/4) = 25 girls.

Imagine Michael, Zoe, and Arjun are planning a treasure hunt. They have a magical map where 1 inch represents 10 miles. To find the treasure, they need to figure out how many inches on the map would represent 150 miles. Can you help them out?

• 10 inches

• 15 inches

• 20 inches

• 25 inches

Answer explanation

To find the number of inches representing 150 miles on the map, divide 150 miles by 10 (miles per inch). The result is 15 inches, so 15 inches on the map would represent 150 miles.

Imagine James has a super cool car that travels 60 miles on just 2 gallons of gasoline. Now, James plans a road trip with his friends Abigail and Lily, and they want to travel 180 miles to reach their favorite beach. How many gallons of gasoline will they need for this exciting trip?

• 3 gallons

• 4 gallons

• 6 gallons

• 9 gallons

Answer explanation

To travel 180 miles at the same ratio of 60 miles per 2 gallons, 180 miles would require 6 gallons of gasoline (180 miles / 60 miles = 3, 3 x 2 gallons = 6 gallons).

Imagine Jackson, Anika, and Benjamin are having a fun day sorting through a magical bag of mixed candies. As they separate the candies by color, they notice an interesting pattern: the ratio of red candies to green candies is 3:4. If they find that there are 12 red candies, can you help them figure out how many green candies are there?

• 9

• 12

• 16

• 18

Answer explanation

Since the ratio of red to green candies is 3:4, and there are 12 red candies, the total number of candies is 12*(4/3)=16 green candies.

Imagine Zoe and Emma are planning a super fun summer project that involves coding a new video game! To make their dream game, they decide to work together for a few weeks. Their progress chart, or as they like to call it, the 'Adventure Tracker', shows that working together for 2 weeks corresponds to 80 hours of coding. Now, if they want to expand their project and work for 5 weeks, how many hours would that be?

• 100 hours

• 200 hours

• 250 hours

• 400 hours

Answer explanation

To find the number of hours corresponding to 5 weeks, we use the ratio 2 weeks = 80 hours. Therefore, 5 weeks correspond to 80 hours * (5 weeks / 2 weeks) = 200 hours.

Oliver, Arjun, and Mia are planning a fun picnic and decide to make a delicious fruit salad. They found a recipe that suggests a ratio of 2 apples for every 3 oranges. If they want to use 18 oranges for their big fruit salad, how many apples do they need to keep the recipe perfect?

• 8 apples

• 12 apples

• 24 apples

• 27 apples

Answer explanation

To maintain the ratio, if you have 18 oranges, you would need 12 apples (18 oranges / 3 oranges per ratio * 2 apples per ratio = 12 apples). Therefore, you need 12 apples.

Imagine you're at a school where the adventure never ends! In this magical place, for every teacher, there are 30 students ready to learn and explore. Now, if the school is lucky enough to have 15 dedicated teachers like Evelyn, Abigail, and Olivia leading the charge, can you guess how many eager students fill the classrooms?

• 450

• 300

• 200

• 45

Answer explanation

To find the number of students, multiply the number of teachers (15) by the ratio (30). 15 * 30 = 450 students.

Imagine Aiden, Avery, and Abigail have formed an unbeatable sports team. For every 3 games they lose, they win 5 games! If our superstar team has won 20 games, can you figure out how many games they've lost?

• 8

• 12

• 15

• 24

Answer explanation

For every 5 wins, there are 3 losses, so the ratio is 5:3. If the team has won 20 games, they have lost 20*(3/5) = 12 games. Therefore, the correct answer is 12.

Imagine Avery, Aiden, and Abigail are having a cookie baking contest. They found a recipe that requires 4 cups of flour for every 6 cups of sugar. They decide to make a half batch and use only 3 cups of sugar. How many cups of flour do they need to win the contest?
