Question

Adam worked 8 hours on Monday, 41⁄4 hours on Tuesday, 61⁄8 hours on Wednesday, 71⁄4 hours on Thursday, and 81⁄8 hours on Friday. Calculate the total number of hours Adam worked for the week. A. 323⁄4 B. 331⁄8 C. 333⁄4 D. 35

Answer 1

C. 33 3/4
8+4+6+7+8=33
1/4+1/4+2/8=3/4
Final Answer 33 3/4

Answer 2

Option C.

Explanation:

Adam's working periods in a week are

Monday = 8 hours

Tuesday = 4
`(1)/(4)=(17)/(4)` hours

Wednesday =
`6(1)/(8)=(49)/(8)` hours

Thursday =
`7(1)/(4)` =
`(29)/(4)` hours

Friday =
`8(1)/(8)=(65)/(8)` hours

Therefore, total working hours = 8 +
`(17)/(4)+ (49)/(8)+ (29)/(4)+ (65)/(8)`

= 8+
`((17+29))/(4)+((49+65))/(8)`

= 8+
`(46)/(4)+(114)/(8)`

= 8+
`(92+114)/(8)`

= 8+
`(206)/(8)`

=
`(64+206)/(8)`

=
`(270)/(8)`

=
`(135)/(4)`

=
`33(3)/(4)` hours

Therefore, Option C. is the answer.
