Table: favorite subject: math 6, science 3, english 4, history 7. the table shows which school subjects are favored by a group of students. predict the number of students out of 400 that would pick science as their favorite subject

This is a ratio problem. First, we need to add the number of students polled.

7 + 4 + 3 + 6 = 20

Next, look at how many out of 20 students selected Science.

3 out of 20.

Say it this way:

3 is to 20 as ? is to 400.

Express it this way:

3/20 = x/400

Cross multiply to eliminate the denominators.

3 x 400 = 20 x  Now solve for x.

1200 = 20 x

x = 60

Check it!

Does 60/400 reduce to 3/20? Yes!

60 students are predicted to select science out of 400
