Complete question :
A dog needs 4/3 liters of water for 2/5 of a day. How many liters of water does the dog need for an entire day?
Answer:
10/3 litres
Explanation:
Given that:
Amount of water needed for 2/5 of a day = 4/3 litres ;
An entire day = 1/ 1 of a day
Hence, If;
2/5 = 4/3 litres of water
1/1 = x
Cross multiply ;
(2/5)x = 4/3
2x /5 = 4/ 3
2x * 3 = 5 * 4
6x = 20
x = 20 /6
x = 10 /3 litres
