7 3/5 + 2 1/2... ignore the whole numbers so 3/5 + 1/2... make the denominator be the same so we can combine the two fractions together. the greatest common multiple (GCM) is 10, so multiple top and bottom of 3/5 by 2 so (3/5)*(2/2)=6/10.... 1/2 must be multiplied by 5 so (1/2)*(5/5)= 5/10.... bring back to equation

=> 6/10 + 5/10 =11/10 or 1 1/10, add the 1 with other whole numbers 1+7+2=10 then bring the 1/10 over so 10 1/10...

so... 7 3/5 +2 1/2 = 10 1/10
