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 = ?
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.
