Which of the fractions 6/12, 9/8, 2/3 is equivalent to 12/18?
You want to look for 12/18 in its minimal form, meaning that you cannot divide the numerator and denominator by the same number, unless that number is 1. So try to work out what the numbers are that divide both 12 and 18. If you can't see it right away, a good place to start would be to see if the fraction is divisible by two:That gives us 6/9. Six and nine are both multiples of 3, so you can divide the fraction by three and get 2/3. So 12/18 = 2/3
