Question

Rosa has 3 3/4 pounds of dough. She uses 1/8 of a pound for one roll. How many folks could be made from rosa's dough

Answer 1

(3 3/4)/(1/8)  rule:  a b/c=(ac+b)/c

(15/4)/(1/8)  rule  (a/b)/(c/d)=(a/b)*(d/c)

(15/4)(8/1)

120/4  simplify by dividing numerator and denominator by 4

30

So with 3 3/4 pounds of dough, she can make 30 rolls.

Answer 2

She can make 30 rolls from her dough.
