Complete question :
Tony worked 4 2/3 on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did. For how many hours did Sonia work on her science project?
Answer: 5 5/6 hours
Step-by-step explanation:
Given the following :
Hours worked by Tony = 4 2/3 hours
Sonia worked 1 1/4 times as long as Tony did.
Number of hours worked by Sonia:
(Hours worked by Tony) × number of times Sonia worked than Tony
(4 2/3) × (1 1/4)
(14 / 3) hours × (5/4)
= (14 * 5) / (3 * 4)
= 70 / 12
= 5 10/12
= 5 5/6 hours
Hence, Sonia worked for 5 5/6 hours on her science project.
