Question 252641
We have several fractions with various denominators.
We need to add 3/8 and 3/5 to see if the sum is less than or equal to 15/16
5*8=40 but 16 is not  a factor of 40
5, 8 and 16 are all factors of 80
So we multiply 3/8 by 10/10 and get 30/80
3/5 by 16/16 and get 48/80
15/16 by 5/5 and get 75/80
So now we add 48/80 and 30/80 and get 78/80 and see that it is more than 75/80
So technically there is not enough sugar but recipes are not usually that strict.
