First, you try to get all the fractions to the same denominator. If you multiply the numerator and denominator of 3/5 by 20, you’ll get 60/100. If you multiply the numerator and denominator of 7/10 by 10, you’ll get 70/100. Since 8/100 equals .08, it’s obviously the least. 70/100 equals 0.70 and 60/100 equals 0.60, so 7/10 is greater than 3/5.
