HOW can you solve this draw a number line to show that 2/3 and 4/6 are equivalent

Answer 1

draw the line
just below it, divide the interval from 0 to 1 into 6 equal parts, each 1/6 long
Just below the 6ths, label the interval in 3rds.
You will see that it takes two 6ths to equal each 3rd.

If that still seems confusing, google number line for many examples and illustrations.
