Steve connected a wire extension that is 3/8 foot long to another wire that is 1/2 foot long. How long is the wire with the extension?

7/8 feet

Step-by-step explanation:

In order to add two frctions you need to make their denominator the same,

3/8 can be kept as it is and we can multiply the top and bottom of 1/2 by 4 in order to ger 4/8. Now it is easier to add together,

3/8 + 4/8= 7/8

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
