Answer:
2 1/4 times
Step-by-step explanation:
A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour. how many times as long in the morning did he work in the afternoon
Note that:
1 hour = 60 minutes
In the moring he worked 2/5 of an hour.
= 2/5 × 60 minutes
= 24 minutes
In the afternoon he worked for 9/10 of an hour
Hence:
9/10 × 60 minutes
= 54 minutes
How many times as long in the morning did he work in the afternoon?
This is calculated as number of minutes worked in the afternoon ÷ Number of minutes worked in the morning
= 54 minutes/24 minutes
= 2 6/24
= 2 1/4 times
Answer:

What you do is you put three on top because a=3 and then you add 5 and 3 to get 8 for the bottom and you get a answer of 3/8 which you cannot simplify with whole numbers
