Question

Stiind ca 2 supra 6 din numarul garoafelor dintr-o gradina sunt rosii , adica 60 , si ca 4 supra 5 din rest sunt albe , cate garoafe sunt de alte culori ?

Answer 1

2/6 ·x=60
⇒x=60/2/6
⇒x=60·6/2
⇒x=360/2
⇒x=180[garoafe total];
⇒60[garoafe rosii];
⇒180-60=120;
⇒4/5 ·120
⇒4·120/5
⇒4·24⇒96[garoafe albe];
⇒180-[60+96]
⇒180-156⇒24[garoafe de alte culori];
