    Answer:

    Step-by-step explanation:

    Let’s set up a percent proportion

    21/70 = x/100

    Now remember:

    in a:b = c:d,

    a is connected to d and b is connected to c

    This means:

    If a is missing, (b*c)/d = a

    If b is missing, (a*d)/c = b

    If c is missing, (a*d)/b = c

    If d is missing, (b*c)/a = d

    In this case, c is missing.

    (21 * 100)/70 = 2100/70 = 30

    Your answer is 30%

    Another way to do this is using benchmark fractions

    We know that 10% of 70 is 7

    So we do 10%*3 = 30% = 21

    This means:

    7 * 3 = 21

    This also means:

    21 = 30% of 70

    I hope this helped, let me know if you have any questions

    Answer:

    30%

    Step-by-step explanation:

    We know that the number of part time employees are 21. The total amount of employees is 70. We can turn these numbers into a fraction: 21/70.

    If we simplify this fraction, we’ll get 3/10, which is 30% as a percentage.
