Answer 1

Answer: 5 5/6

Step-by-step explanation:
`4 (2)/(3) x 1 (1)/(4) = (35)/(6) \\`

You can simplify
`(35)/(6)` to
`5(5)/(6)`

Hope this helps! :)

Answer 2

To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:


`4 (2)/(3) * 1 (1)/(4) \\ = (14)/(3) * (5)/(4) \\ = (70)/(12) \\ = 5 (10)/(12) \\ = 5 (5)/(6)`
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!
