Let's solve each of the ratio word problems step by step. These are all based on
ratios, which compare two quantities.

Problem 1:
The ratio of tomatoes to red apples is 2:5. If there are 20 tomatoes, how many red apples are there?
Step-by-step:
- The ratio is
tomatoes : red apples = 2:5
- This means for every
2 tomatoes, there are
5 red apples
- We are told there are
20 tomatoes
- We need to find how many red apples correspond to 20 tomatoes
Set up a proportion:
$$
\frac{2}{5} = \frac{20}{x}
$$
Cross-multiply:
$$
2x = 5 \times 20 = 100
$$
$$
x = \frac{100}{2} = 50
$$
✔ Answer: 50 red apples

Problem 2:
The ratio of berries to oranges is 10:1. If there are 25 oranges, how many berries are there?
- Ratio:
berries : oranges = 10:1
- So, for every
1 orange, there are
10 berries
- There are
25 oranges, so multiply:
$$
25 \times 10 = 250
$$
✔ Answer: 250 berries

Problem 3:
The ratio of potatoes to turnips is 1:1. If there are 472 potatoes, how many turnips are there?
- Ratio:
potatoes : turnips = 1:1
- This means they are equal in number
- So, if there are 472 potatoes, then there are also
472 turnips
✔ Answer: 472 turnips

Problem 4:
The ratio of pears to green apples is 1:3. If there are 150 green apples, how many pears are there?
- Ratio:
pears : green apples = 1:3
- For every
3 green apples, there is
1 pear
- We have 150 green apples → divide by 3 to get the number of pears:
$$
\frac{150}{3} = 50
$$
✔ Answer: 50 pears

Problem 5:
The ratio of bananas to melons is 30:1. If there are 300 bananas, how many melons are there?
- Ratio:
bananas : melons = 30:1
- So, 30 bananas → 1 melon
- 300 bananas → ?
Divide 300 by 30:
$$
\frac{300}{30} = 10
$$
✔ Answer: 10 melons

Problem 6:
The ratio of blueberries to strawberries is 1:7. If there are 210 strawberries, how many blueberries are there?
- Ratio:
blueberries : strawberries = 1:7
- For every
7 strawberries, there is
1 blueberry
- So, divide 210 by 7:
$$
\frac{210}{7} = 30
$$
✔ Answer: 30 blueberries
