Daca o rata si jumatate, intr-o zi si
jumatate, fac un ou si jumatate, cate
oua vor face trei rate in trei zile?
Correct answer: answer number 3 - 6 oua
1.5 rate, in 1.5 zile, fac 1.5 oua =>
1 rata, in 1.5 zile, face 1.5/1.5
oua => 1 rata, in 1.5 zile, face 1
ou => 1 rata, in 1 zi, face 1/1.5
oua => 1 rata, in 3 zile, face 3/1.5
oua => 3 rate, in 3 zile, fac 9/1.5
oua 9/1.5 = 90/15 = 6
