Bob has 1 2/3lb of candy. he spilled 3/4 of his candy on the ground. how many pounds of candy did bob spill? solve with a pictorial model.

 1   1/4 lb   (1.25 lb)

Step-by-step explanation:

1   2/3 is a mixed number

Convert in improper fraction    :5/3 lb

5/3 * 3/4 = 15/12 = 5/4 = 1  1/4

5 divided into 4 = 1.25  (or 1  1/4)

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
