Question 298712
A cat, a fox and a dog share a portion of 450 grams of meat. If two foxes eat as much as three cats and two cats eat as much as a dog, how many grams of meat does the fox eat?

let dog eat x grams

cat eats x/2 

3 cats eat 3x/2 

2 foxes eat 3x/2

each fox eats 3x/4

x+x/2+3x/4=450 

4x+2x+3x /4  = 450

10x= 450*4

10x=1800
x=180 
x= 90 grams

3*90 /4 = 270/4  = 67.50 grams eaten by fox
