Question

Bryce has to complete 100 minutes of writing every ten days. He writes for 10 minutes each day. What fraction of his writing requirement does Bryce complete in five days? Write in simplest form.

Answer 1

He writes 10 minutes a day. 
After 5 days, he writes for 50 minutes because 
10 x 5 = 50
50 is 1/2 of 100. He has done 1/2 of his requirement. 
Hope this helps!

Answer 2

Since he completes 10 minutes each day for five days, he completes 50 minutes.

The percentage of his total requirement would be 50/100 = 0.5 = 50%.
