Question

Mary filled a water cooler with 6 1\2 gallons of water. She forgot to close the plug and 2 5\6 gallons leaked out. How many gallons of water remain in the cooler?

Answer 1

`remining\ gallons\ of\ water= water\ filled-\ water\ which\laked\ out\\\\ remining\ gallons\ of\ water=6(1)/(2)-2(5)/(6)=6(3)/(6)-2(5)/(6)=\\\\5(9)/(6)-2(5)/(6)=3(4)/(6)=3(2)/(3)\\\\In\ the\ cooler\ remained\ 3(2)/(3)gallons\ of\ water.`
