On the planet Flarp, 3 floops equal 5 fleeps, 4 fleeps equal 7 flaaps, and 2 flaaps equal 3 fliips. How many floops are equal to 35 fliips? No Answer Choices Solution (from the MGMT SG book):35 fliips x 2 flaaps/3 fliips x 4 fleeps/7 flaaps x 3 floops/5 fleeps = 8 floops
I understand their solution but am puzzled as to why my 1st method brings up the completely wrong answer
My approach was such:
Given:
3 Floops = 5 Fleeps Eq. A 4 Fleeps = 7 Flaaps Eq. B 2 Flaaps = 3 Fliips Eq. C
Find:
X Floops = 35 Fliips
Approach:
Eq. C x 7: 14 Flaaps = 35 Fliips
Eq. B x 2: 14 Flaaps = 8 Fleeps
Eq. A x 8/5: 8/5*3 Floops = 8 Fleeps
Combine your new equations
35 Fliips = 14 Flaaps = 8 Fleeps = 8/5*3 Floops Thus 35 Fliips = 24/5 Floops?

No Answer Choices Solution (from the MGMT SG book): 35 fliips x 2 flaaps/3 fliips x 4 fleeps/7 flaaps x 3 floops/5 fleeps = 8 floops
I understand their solution but am puzzled as to why my 1st method brings up the completely wrong answer

Eq. C x 7: 14 Flaaps = 35 Fliips
Eq. B x 2: 14 Flaaps = 8 Fleeps
Eq. A x 8/5: 8/5*3 Floops = 8 Fleeps
Combine your new equations
35 Fliips = 14 Flaaps = 8 Fleeps = 8/5*3 Floops Thus 35 Fliips = 24/5 Floops? Hi, Your Mistake is highlighted above Eq. C x 7: Gives you 14 Flaaps = 21 FliipsSuggestion: In the questions of Conversion, It's best to convert the the higher units into smaller units instead of converting the other way roundLets Solve as per your method Eq. C x (35/3): Gives you 70/3 Flaaps = 35 Fliips Now, Eq. B x (10/3): 70/3 Flaaps = 40/3 Fleeps Now, Eq. A x (8/3): 8 Floops = 40/3 Fleeps i.e. 8 Floop should be the CORRECT answer

Thank you, redid the sum multiple times from scratch and for some reason I kept making the same calculation error.
Appreciate the tip too, it makes sense

On the planet Flarp, 3 floops equal 5 fleeps, 4 fleeps equal 7 flaaps, and 2 flaaps equal 3 fliips. How many floops are equal to 35 fliips? a = floops b = fleeps c = flaaps d = fliips x * a = 35 * d where "x" is the unknown number of floops
3a = 5b = > (3a/5) = b 4b = 7c = > 4 (3a/5) = 7c => (12a/35) = c 2c = 3d => 2 (12a/35) = 3d => (24a/35) = 3d cross multiply (24/3) a = 35 d 8 * a=35 * d
8
