over the weekend, Ed spent 1 1/4 hours doing his math homework and 1 3/4 hours doing his science project. Altogether, how much time did Ed spend doing homework over the weekend?
You have to add 1 1/4 + 1 3/4. Since they have common denominators you can just add all the numbers, 1+1=2, 1+3=4 since 4/4 is equal to one, you would add a one to the 2, so the answer would be 3. So Ed spent 3 hours doing homework during the weekend.
Answer:
3 hours
Step-by-step explanation:
We have that,
Time spent by Ed to do math homework = \(1\frac{1}{4}\) = \(\frac{5}{4}\) hours.
Time spent by Ed to do science homework = \(1\frac{3}{4}\) = \(\frac{7}{4}\) hours.
Thus, total time spent by Ed = Time for math + Time for science
i.e. Total time spent by Ed = \(\frac{5}{4}\) + \(\frac{7}{4}\)
i.e. Total time spent by Ed = \(\frac{12}{4}\)
i.e. Total time spent by Ed = 3 hours.
Hence, the time spent by Ed doing his homework is 3 hours.
