Final answer:
After converting Ravi's rope length into centimeters, and subtracting the length given to his brother, Ravi has 132 centimeters of rope left.
Step-by-step explanation:
Ravi started with 2.25 meters of rope and gave away 93 centimeters of it. To find out how much rope Ravi has left, we first need to make sure that both measurements are in the same unit. We can convert meters to centimeters by multiplying by 100 since 1 meter equals 100 centimeters.
So, Ravi's rope in centimeters is 2.25 meters × 100 = 225 centimeters. Now, we subtract the amount he gave to his brother: 225 centimeters - 93 centimeters = 132 centimeters.
Therefore, Ravi has 132 centimeters of rope left after giving some to his brother.
