Im getting really confused on making decimals back into fractions it takes me way too long going through each answer choice. is there a easier way? for ex. express 15.56 as a mixed number in lowest terms. a.) 15 28/45b.) 15 14/25c.) 389/25d.) 469/30

I don't know how to explain it that well, but maybe you could try doing

15 and simplifying the 56 over 100 to 28 over 50, it would at least make it easier.

(x+3)(x+7)

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
