Two <em>possible answers</em> are:
5/16 and 3/8.
Explanation:
To create a fraction equivalent to a given fraction, you multiply the numerator and denominator by the same number. This means for 5/8, we could have:
5/8; (5*2)/(8*2)=10/16; (5*3)/(8*3)=15/24; etc.
For 1/2, we could have:
1/2; (1*2)/(2*2)=2/4; (1*3)/(2*3)=3/6; etc.
For this case, the first thing we must do is define variables.
x: amount of time Miguel uses to complete the task.
y: amount of time Maria uses to complete the task.
We write the system of equations:
x + y = 60
y = (1/2) x
Solving the system we have:
x = 40 minutes
y = 20 minutes
