The best thing to do is either to find a common denominator or convert them to decimals. I will find a common denominator. A common denominator of 3 and 5 is 15. You multiply the first fraction by 5 2*5= 10 This then becomes 10/15 You then multiply the second by 3. 4*3= 12 Therefore, this becomes 12/15 As the second of these fractions is larger, this means that 4/5 is larger. The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8 Hope this helps :)
