Question

There are 12 inches in 1 foot. what fact family would you use to find the number of inches in 2 feet?

Answer 1

So like you said there are 12 inches in a foot so we can set it up like this:
x = 12
x is the feet and the variable is the inches
so if u need to find 2 feet it would be
2x = 24
24 is the answer

Answer 2

The fact is that 1 foot equals to 12 inches, so I will just have to add 12+12 or just multiply 12x2 which is 24. There are 24 inches in 2 feet.

Hope I helped:)
