Answer:
1 to 2
1:2
1/2
Step-by-step explanation:
Ratios can be written in three forms:
A to B
A:B
A/B
Ratios are also simplified by reducing to lowest terms like fractions are.
This problem's ratio is:
minutes lifted weights to total minutes workout
The number of minutes lifting weights is in the question: 25.
To find the total minutes of his workout, add the number of minutes he spent for all of the activities:
Total minutes = warm-up + lifting weights + treadmill
Total minutes = 10 + 25 + 15
Total minutes = 50
The ratio before simplifying is 25/50.
This ratio can be reduced to lowest terms. Both sides are divisible by 25.
25/25 = 1
50/25 = 2
The ratio in lowest terms is 1/2.
It can also be written as 1 to 2 or 1:2.
