Click me to Read more Question & Answer of Ratio and ProportionThe ratio of land: water = 1: 2 In the northern hemisphere the ration of land: water = 2: 3 Note: Earth is divided equally into two hemispheres called northern hemisphere and southern hemisphere. i.e., the northern hemisphere is 50% of the total earth. We can say southern hemisphere = total area- northern hemisphere. To make the northern hemisphere 50% of the total area Multiply the ratio of the earth by 10 and northern hemisphere by 3 Now, earth's ratio Land: water = 1*10: 2*10 = 10: 20............... (i) Northern hemisphere's ratio = 2*3: 3*3 = 6: 9...................... (ii) Subtract equation i by ii Hence, southern hemisphere = 10- 6: 20-9 = 4: 11
