Answer :
To solve the problem, we'll start by converting all the measurements to the same unit, meters, so that we can easily perform the arithmetic operations.
1. Convert 120 cm to meters:
- We know that 1 meter equals 100 centimeters.
- Therefore, to convert 120 cm to meters, divide by 100:
[tex]\[
120 \, \text{cm} = \frac{120}{100} = 1.2 \, \text{m}
\][/tex]
2. Convert 2.5 × 10³ mm to meters:
- 1 meter is equal to 1000 millimeters.
- So, we convert 2.5 × 10³ mm to meters by dividing by 1000:
[tex]\[
2.5 \times 10^3 \, \text{mm} = \frac{2.5 \times 10^3}{1000} = 2.5 \, \text{m}
\][/tex]
3. Value already in meters:
- We are given 1.1 meters, which is already in the required unit.
4. Perform the arithmetic operation:
- Add the converted lengths and subtract the given length in meters:
[tex]\[
1.2 \, \text{m} + 2.5 \, \text{m} - 1.1 \, \text{m} = 2.6 \, \text{m}
\][/tex]
Thus, after performing the operations, the result is 2.6 meters. Therefore, the answer to the question is:
2.6 m
1. Convert 120 cm to meters:
- We know that 1 meter equals 100 centimeters.
- Therefore, to convert 120 cm to meters, divide by 100:
[tex]\[
120 \, \text{cm} = \frac{120}{100} = 1.2 \, \text{m}
\][/tex]
2. Convert 2.5 × 10³ mm to meters:
- 1 meter is equal to 1000 millimeters.
- So, we convert 2.5 × 10³ mm to meters by dividing by 1000:
[tex]\[
2.5 \times 10^3 \, \text{mm} = \frac{2.5 \times 10^3}{1000} = 2.5 \, \text{m}
\][/tex]
3. Value already in meters:
- We are given 1.1 meters, which is already in the required unit.
4. Perform the arithmetic operation:
- Add the converted lengths and subtract the given length in meters:
[tex]\[
1.2 \, \text{m} + 2.5 \, \text{m} - 1.1 \, \text{m} = 2.6 \, \text{m}
\][/tex]
Thus, after performing the operations, the result is 2.6 meters. Therefore, the answer to the question is:
2.6 m
