Answer:
Isabella 30 min; Mia 90 min.
Step-by-step explanation:
To find the percentage of a number use this formula: %/100 × x/1
Let me help you understand this formula.
According to the word problem, Daniel finished his homework in 60 minutes. Isabella finished his work in 50% of Daniel's time (60). And, Mia finished her work in 150% of Daniel's time.
To find out how much time it took Isabella to finish her homework, we need to find the 50% of 60.
%/100 × x/1
50/100 x 60/1 = 3000/100 = 30
50% of 60 is 30; Isabella finished her homework in 30 minutes.
Mia finished her homework in..
%/100 × x/1
150/100 x 60/1 = 9000/100 = 90
90 is 150% of 60; Mia finished her homework in 90 minutes (1 hour and 30 minutes).
