Final answer:
Ranjeet spent a total of 3 3/4 hours on homework and allocated 1 1/2 hours to mathematics. By subtracting the time spent on mathematics from the total time, it is determined that he spent 2.25 hours on other subjects.
Step-by-step explanation:
To determine the time Ranjeet spent doing homework for other subjects besides mathematics, we need to subtract the time spent on mathematics from the total time spent on homework. Ranjeet spent 3 3/4 hours in total, which is the same as 3.75 hours. He devoted 1 1/2 hours to mathematics, or 1.5 hours. Now, we perform the subtraction: 3.75 hours - 1.5 hours = 2.25 hours. Therefore, Ranjeet spent 2.25 hours doing homework for other subjects.
To find the time spent doing work for other subjects, we need to subtract the time spent on mathematics from the total time spent on homework.
Ranjeet spent 3 3/4 hours on homework, and 1 1/2 hours on math. To find the time spent on other subjects, we subtract the time spent on math from the total time spent on homework:
3 3/4 hours - 1 1/2 hours = 2 1/4 hours
Therefore, Ranjeet spent 2 1/4 hours on other subjects.
