Can you give me proportion problems?

Sagot :

A King named Jarret, has three childrenr: Janos, Jerry, and Alexa. The oldest is Janos, Alexa is the youngest and is the only daughter of King Jarret. 
The king have 300 Hectares of farm, he is going to divide it by his children in the proportion of 5: 3: 2 , arrange according to age.
How many hectares of farm does Janos, Jerry and Alexa has?

5 + 3 + 2 = 10
5/10 goes to Janos, 3/10 goes to Jerry, and 2/10 goes to Alexa.
Janos : 5/10 * 300 = 150
Jerry : 3/10 * 300 = 90
Alexa : 2/10 * 300 = 60
All : 10/10 * 300 = 300

So therefore, Janos will get 150 hectares of farm, Jerry will get 90 hectares of farm, and Alexa will get 60 hectares of farm from their father Kind Jarret.
