Answers

Answer 1
Answer: 20 dollars in 5 hours
Answer 2
Answer: if she earns $12 in 3 hours we need to find out how much she makes in 1 hour.

To do that we divide the total money by the hours 12/3 = $4 per hour

Then we multiply the number of hours times the per hour rate: 5 * $4 = $20

Anna will make $20 in 5 hours

On Monday John ate 1/6 of a carton of eggs. If there are 12 eggs in the carton how many eggs are left

Answers

Answer:

12 divided by 6 is 2.  

Step-by-step explanation:

There are 12 eggs in the carton, right? So, split the number of eggs into 6 groups. There are 2 eggs in each of the six groups. John eats an entire group of eggs (two eggs). What is twelve minus two?

12 - 2 = 10 eggs left (left behind are 5/6 of the eggs in the carton).

Hope this helps.

the answer is 2 because if you divide 12 by 6 one sixth is equal to 2

Can you tell me this two? Thanks
