PROBLEM: Christian has two-thirds of a pound of chocolate chips. Kaylee has 0.25 pounds of chocolate chips. How much more do they need to have a whole pound of chocolate chips?

Here's the solution!

They need to either convert the fraction to a decimal or the decimal to a fraction: two-thirds = 0. 666…, and 0.25 = one-fourth. Two-thirds + one-fourth = eleven-twelfths, so they would need one-twelfth of a pound more. 0.666… + 0.25 = 0.916…, so they would need 0.083… pounds more.
