Rekha and Sabitha want to get their house painted. They have 35.75 litres of paint. The 3 bedrooms together need 17.75 litres of paint, the dining room needs 9 litres, the lounge needs 10.25 litres and the kitchen and the bathroom both together need 1.75 litres each. Do they have enough paint? If so, how much paint is left over? If not, how much more must they buy?
