Question

Of the 1st graders who were asked, 1/6 like math best, 2/3 like reading best, and 12 like science best. How many first graders were asked their favorite subject? THINK: Into how many equal parts should the picture be divided? Draw a picture to solve the problem.

Answer 1

Let's start by adding the fractions.

1/6 + 2/3 = 1/6 + 4/6 = 5/6

That means that 1/6 of the first graders like science best (6/6 - 5/6 = 1/6).

Then set up an equation with x = total first graders.

1/6 x = 12
x = 12 / 1/6 = 12 * 6
x = ?

Answer 2

72

Answer 3
