Set up a proportion to solve. 440 pounds of flour per 1000 loaves is to x pounds of flour per loaf.
x= # of pounds of flour per loaf
440/1000= x/1
cross multiply
(440*1)= (1000*x)
440= 1000x
divide both sides by 1000
440/1000= x
0.44= x
x= 0.44 pounds
ANSWER: 0.44 pounds of flour are used in each loaf.
Hope this helps! :)
