Real-life math problems worksheet for students, including word problems about measurements, fractions, and counting.

Problem 1: Jump Rope Length

Question: A jump rope is supposed to be 1.5 m long, but it is only 0.9 m long. How much of the skipping rope is left?

#### Solution:
1. Identify the given values:
- The intended length of the jump rope: \( 1.5 \) meters.
- The actual length of the jump rope: \( 0.9 \) meters.

2. Determine how much of the rope is missing:
- Subtract the actual length from the intended length:
\[
1.5 \, \text{m} - 0.9 \, \text{m} = 0.6 \, \text{m}
\]

3. Conclusion:
- The skipping rope is missing \( 0.6 \) meters.

Answer:
\[
\boxed{0.6 \, \text{m}}
\]

Problem 2: Money Distribution

Question: Maria has three notes of 200. Each note can be used for 425 ml. How many liters does she have altogether?

#### Solution:
1. Identify the given values:
- Maria has 3 notes of 200 each.
- Each note can be used for 425 ml.

2. Calculate the total amount of money:
- Total money = \( 3 \times 200 = 600 \).

3. Determine the total volume in milliliters:
- Since each note corresponds to 425 ml, the total volume is:
\[
3 \times 425 \, \text{ml} = 1275 \, \text{ml}
\]

4. Convert milliliters to liters:
- There are 1000 ml in 1 liter.
- Convert 1275 ml to liters:
\[
\frac{1275}{1000} = 1.275 \, \text{liters}
\]

5. Conclusion:
- Maria has a total of \( 1.275 \) liters.

Answer:
\[
\boxed{1.275 \, \text{L}}
\]

Problem 3: Tree Counting

Question: Tony saw three trees on one side of a street window. He sees twice as many trees on the other side of the window. How many trees does Tony see?

#### Solution:
1. Identify the given values:
- Trees on one side of the window: \( 3 \).
- Trees on the other side of the window: Twice as many as on one side.

2. Calculate the number of trees on the other side:
- Trees on the other side = \( 2 \times 3 = 6 \).

3. Calculate the total number of trees:
- Total trees = Trees on one side + Trees on the other side:
\[
3 + 6 = 9
\]

4. Conclusion:
- Tony sees a total of \( 9 \) trees.

Answer:
\[
\boxed{9}
\]

Problem 4: School Playground Space

Question: A school playground is 180 m long and 60 m wide. 60% of the area is used by the 3rd grade children, and the rest is used by the 4th grade children. How much space is used by the 4th grade children?

#### Solution:
1. Identify the given values:
- Length of the playground: \( 180 \, \text{m} \).
- Width of the playground: \( 60 \, \text{m} \).
- Percentage of the area used by 3rd grade children: \( 60\% \).
- Remaining percentage for 4th grade children: \( 100\% - 60\% = 40\% \).

2. Calculate the total area of the playground:
- Area = Length × Width:
\[
180 \, \text{m} \times 60 \, \text{m} = 10800 \, \text{m}^2
\]

3. Calculate the area used by the 4th grade children:
- Area used by 4th grade children = \( 40\% \) of the total area:
\[
0.40 \times 10800 \, \text{m}^2 = 4320 \, \text{m}^2
\]

4. Conclusion:
- The 4th grade children use \( 4320 \, \text{m}^2 \) of the playground.

Answer:
\[
\boxed{4320 \, \text{m}^2}
\]

Problem 5: Change Calculation

Question: Mona has a coin that costs $2.50. She gives it to the cashier. What must the change be received?

#### Solution:
1. Identify the given values:
- Cost of the item: \( \$2.50 \).
- Amount given by Mona: \( \$5.00 \).

2. Calculate the change:
- Change = Amount given - Cost of the item:
\[
\$5.00 - \$2.50 = \$2.50
\]

3. Conclusion:
- The change received should be \( \$2.50 \).

Answer:
\[
\boxed{2.50}
\]

Problem 6: Juice Box Volume

Question: A box of juice contains 192 cl. Half of the juice is left. How much is the juice left?

#### Solution:
1. Identify the given values:
- Total volume of juice in the box: \( 192 \, \text{cl} \).
- Half of the juice is left.

2. Calculate the remaining volume:
- Remaining volume = \( \frac{1}{2} \) of the total volume:
\[
\frac{192}{2} = 96 \, \text{cl}
\]

3. Conclusion:
- The amount of juice left is \( 96 \, \text{cl} \).

Answer:
\[
\boxed{96 \, \text{cl}}
\]
