Inez waters her plants every two days. She trims them every 15 days. She did both today. When will she do them both again?

shtirl [24]

The answer is 30 days.

The solution for this is to find the least common multiple. By getting the multiple of both numbers.

Multiples of 2: 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40…..

Multiples of 15: 15,30,45,60,75……..

The Least Common Multiples of 2 and 15 is 30. So, Inez will do them both again in 30 days.

The least common multiple (LCM) of two numbers is the smallest number that is multiple by the both number.

Answer:

2/9

Step-by-step explanation:

Since there are 18 total eggs (cracked, white, brown) we can say that the denominator will be 18.

There are 8 white eggs, and when half of those are cracked there will be 4 uncracked and 4 cracked, so 4/18.

Simplify 4/18 to 2/9 and there is your answer.
