Claire went home after school and told her mother that 1 whole is the same as 2/2 and 6/6. Her mother asked why, but Claire couldn't explain. Use a number line and words to help Claire show and explain why. 1 = 2/2 = 6/6.

2/2 means 1/2 and 1/2
The distance between 0 and 1 and then 1/2 again we will end up at 1. Think of cutting the distance from 0 to 1 into two equal pieces and Together those pieces equal 1 whole. we do the same and cut the distance into 6 and then take six such pieces we again get the whole distance from 0 to 1 or one whole.

I’m confused as to what you are asking 66 2/3 percentage wise
