luann talked on her cell phone for 180 minutes using 3/7 of her total monthly minutes. find out how many minutes she gets to talk in one month using two methods

Answer: 420 minutes.

Step-by-step explanation:

The first method could be to do 180 / 3 then multiply that by seven:

180 / 3 = 60

60 * 7 = 420.

That solution would be to find out what 1/7 of her total monthly minutes is, and then multiplying it in order to get the total monthly minutes.

Another solution could be to divide 180 by 3/7:

180 / (3/7) = 420
