Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?

54 years

Step-by-step explanation:

Given that :

Let :

Ann's age = x

Mary's age = x/2

Donald's age = x/3

x + x/2 + x/3 = 99

Take the L. C. M

(6x + 3x + 2x) / 6 = 99

11x / 6 = 99

11x = 99 * 6

11x = 594

x = 594 / 11

x = 54

Hence, Ann is 54 years

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
