Question

Arnold’s entire workout consisted of 10 minutes of warm-up exercises, 25 minutes of lifting weights, and 15 minutes on the treadmill. What was the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout?

2 Answer

  • Answer:

    1:2

    Step-by-step explanation:

    Find the ratio of the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout and simplify it

    25:10+25+15

    25:50

    1:2

  • 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.
