Ethan needs two pieces of string that are 10 and a half and 12 inches long. Determine the total length of the two strings.

Here’s a sketch of two pieces of string. If we say that the yellow string is 10 and a half inches long and the red string is 12 inches long, how can we add them together? Let’s start by dealing with the fractional pieces.

For the 10 and a half inch long piece of string, we have one-half. For the 12-inch-long piece of string, we have no fractional parts. Basically, we can say one-half plus zero. One-half plus zero equals one-half. And then we move on to our whole numbers. We just add 10 plus 12, equals 22.

If we put our whole number pieces and our fractional pieces together, we get 22 and one-half. We don’t wanna forget our units though. We’re dealing with inches, 22 and one-half inches. Ethan has 22 and one-half inches of string.
