OpenStudy (mathstudent55):

In a year, there are 4 months with 30 days. How many months are there with other than 30 days?

OpenStudy (anonymous):

idk febuary

OpenStudy (mathstudent55):

How many months are there in a year?

OpenStudy (anonymous):

12

OpenStudy (anonymous):

so 8

OpenStudy (mathstudent55):

Good. If 4 month of those 12 have 30 days, how many months don't have 30 days?

OpenStudy (mathstudent55):

Right, 8.

OpenStudy (mathstudent55):

So there are 4 months with 30 days and 8 months with other than 30 days.

OpenStudy (mathstudent55):

The ratio is (number of months with 30 days) to (number of months of other than 30 days)

OpenStudy (anonymous):

not a fast typer

OpenStudy (anonymous):

so 4/8

OpenStudy (anonymous):

or c

OpenStudy (mathstudent55):

The ratio is \(\bf \color{red}{(number~ of~ months~ with ~30 ~days)}\) to \(\bf \color{red}{(number~ of~ months~ of~ other~ than~ 30 ~days)}\) or \(\bf \color {red}{4} ~ to ~ \color{red}{8}\)

OpenStudy (mathstudent55):

Be careful. c is 2 to 1 The larger number is first, 2, then the smaller number 1. Here it's 4 to 8, with the smaller number first.

OpenStudy (mathstudent55):

4 to 8 can be reduced to 1 to 2 by dividing both numbers by 4. Choice c is 2 to 1, not 1 to 2.

OpenStudy (anonymous):

ohhhh

OpenStudy (anonymous):

i mean b

OpenStudy (mathstudent55):

Good!

OpenStudy (anonymous):
