I have fraction word problem made from a recipe. If it takes 2 1/2 cups of oatmeal to make 30 cookies. How much oatmeal will it take to make 120 cookies?

  • fractions word problems fifth gradee -

    Since 30 x 4 = 120, you must then multiply 2 1/2 by 4 to find out.

    30 can go into 120 4 times. So you have to multiply the 2 1/2 cups 4 times.

    2 1/2 x 4 = your answer!

    hope this helped!

    They are both right. The easiest way to do this is to make a proportion, though. 2.5/30=x/120, Cross multiply 30x=300, solve for x.
