We want the ratio of calories of an orange to a cookie and are told that an orange has 35 calories and a cookie has 130 so:
O:C=35:130
The greatest common factor of 35 and 130 is the product of the shared primes of the numbers prime factorization.
35=5*7 and 130=2*5*13, so the GCF is just 5, so divide each term by 5
O:C=7:26
You need to make the fractions into improper fractions with the same denometer. 3 4/7 to an improper fraction is 25/7 and 3 1/4 is 13/4. Now get common denometers, in going to choose 28. 100/28 is the same as 25/7 and 91/28 is the same as 13/4. Now subtract 100/28 and 91/28 and you get 9/28. So you need to add 9/28 of a cup.
