These ratio practice problems are great for all ages for those who are looking to improve their ratio problem solving skills. Questions and answers are available in PDF format as printable worksheets on the link below as a free download.
175 seagulls
We know that the people ratio is 5 seagulls : 2 crabs meaning there are a total of 7 animals per grouping (5 seagulls + 2 crabs).
We then know that there 2 crabs per every 7 animals. Since we know there are 70 crabs, we can calculate the total animals as 7/2 * 70 = 245.
We also know that there 5 seagulls per every 7 animals. Then to calculate total seagulls we take 245 * 5 / 7 = 175 seagulls.
19.68 feet
The ratio is 1 meter : 3.28 feet.
Therefore 6 meters = ? feet
So we need to multiply the feet by 6 to keep the ratio the same.
3.28 x 6 = 19.68
There 19.68 feet is equal to 6 meters.
24 goats
We know that the people ratio is 2 sheep : 3 pigs : 4 goats. This means there are a total of 9 animals per grouping (2 sheep + 3 pigs + 4 goats).
We then know that there 2 sheep per every 9 animals. Since we know there are 12 crabs, we can calculate the total animals as 9/2 * 12 = 54.
There are 4 goats per every 9 animals. To calculate total goats we take 54 * 4 / 9 = 24 goats.
21 fish in total
We know that the people ratio is 2 blue fish : 4 green fish. This means there are a total of 6 fish per grouping (2 blue + 4 green).
We know there are 14 green fish, so can calculate the total fish as 6/4 * 14 = 21.
1 : 6
There are 30 objects (5 rows x 6 columns) in the image. There are only 5 cars.
Therefore 30/5 = 6
The ratio of cars to total objects is 1 : 6.
Three times
The ratio of wheels can be found be dividing both by the highest common factor (18).
18 / 18 = 1 and 54 / 18 = 3. Therefore the ratio of wheels is 1 : 3.
Truck A therefore has three times fewer wheels.
3 : 2
There are 15 footballs and 10 cars in the image.
If we divide both by 5 (the highest common factor) we end up with 3 footballs to 2 cars or 3 : 2.
1 cup
The ratio we have is 2 cups flour : 1/4 sugar.
8 cups of flour is 4 times the number we need for 1 cake therefore we need 4 times the amount of sugar.
4 x 1 / 4 = 1
32
The total count of clothing items per group would be 4 + 6 + 3 = 13.
That means there are 13 / 3 * 24 = 104 items of clothing in the store.
104 * 4 / 13 = 32.
2 : 3
In order to determine the ratio, you need to find the highest common factor for both. This is 2 being the highest number both can be divided by.
6 / 2 = 3 and 4 / 2 = 2.
Therefore the ratio of strawberry to vanilla is 2 : 3.
