Hey there! I'm happy to help!

We want to see how many times bigger 2/5 is than 9/10. Let's call how much bigger 2/5 is b and solve below.

9/10b=2/5 (2/5 is b times larger than 9/10)

We divide both sides by 9/10, so your division would be 2/5÷9/10.

b=4/9

Therefore, the builder worked 4/9 times as long in the morning as he did in the afternoon.

Have a wonderful day! :D

Answer:

2/9 times

Step-by-step explanation:

This is because 2/5 divided by 9/10 = 10/45 wich if we simplify it we get 2/9 so that's why 2/9 is the right answer.
