**Challenge** How many pancakes did I make if I used exactly 4 cups of water?
If you forget how to solve a proportion, follow this example by Harrison!
1. 1 x x= 8 1/3
ReplyDelete- = -
6 50
2. 1.5 x x= 2 1/2
___ = ___
12 20

TO QUESTION #1
ReplyDelete6:1=50:x CROSS MULTIPLY AND GET
50 = 6x X=
- - DIVIDE 6 BY 50
AND GET 8 AND 2 6THS
6 6 THEN REDUCE AND YOUR ANSWER IT IS 8 AND 1 THIRD
8 AND 1 THIRD
TO ANSWER QUESTION #2
ReplyDeleteFIRST YOU DO 6(OVER) 3 FOURTHS = 20(OVER)X
CROSS MULTIPLY AND GET 6x = 15
- -
6 6 SOLVE THAT AND GET X = 15 CUPS TO MAKE
20 PANCAKES
1.2/18=x/50
ReplyDeletex=5.5cups to make 50 pancakes
2.3/18=x/20=3.3cups of water
3.1.5/12/4/x=32 pancakes

Tarah,
ReplyDeleteExcellent job. All three answers are correct! Good job on setting up each proportion!!
Taylor,
ReplyDeleteOn your answer to question #2 you did set up the proportion correctly, however, you needed to divide both sides of the equation by 6 to keep a balance. 6x/6 would give you X by itself and 15/6 would have given you 2 1/2 cups of water!
Good job on the proportion though!
JT,
ReplyDeleteCheck out Tarah's proportions for numbers 1 and 2 in the comment above.
Number 3, the CHALLENGE question is perfect though!! Good job!
