Question

Last week you worked the following hours: monday, 5 ½ wednesday, 6 ¾ friday, 4 ½ how many hours did you work in all last week

Answer 1

16 3/4 hours total is the answer

Answer 2

Answer:
`16(1)/(4)\text{ hours}`

Explanation:

Given : The number of hours you did study on Monday =
`5(1)/(2)\text{ hours}`

The number of hours you did study on Wednesday =
`6(1)/(4)\text{ hours}`

The number of hours you did study on Friday =
`4(1)/(2)\text{ hours}`

Then the total hours you study is given by :-

`5(1)/(2)+6(1)/(4)+4(1)/(2)\\\\=(11)/(2)+(25)/(4)+(9)/(2)\\\\=(22+25+18)/(4)\\\\=(65)/(4)=16(1)/(4)`

Hence, the total hours you study in last week =
`16(1)/(4)\text{ hours}`
