Question

Susie spent 4 1/4 hours on Monday and 3 5/8 hours on Tuesday working on a history project. About how long did she spend working on the project?

Answer 1

Answer:

As per the statement:

Susie spent time on Monday =  $4\frac{1}{4}$ = $\frac{17}{4}$ hours

and

Susie spent time on Tuesday = $3\frac{5}{8} = \frac{29}{8}$ hours.

Total time she spend working on the history project = $\frac{17}{4} + \frac{29}{8}$

Take LCM of 4 and 8 is, 8

⇒$\frac{34+29}{8} = \frac{63}{8} = 7\frac{7}{8}$ hours.

Therefore, total time did she spent working on the project is, $7\frac{7}{8}$ hours.

Answer 2

4 1\4 +3 5\8
(4+3=7)
1\4+5\8=2+5=7\8
answer=7 7\8
