Answer:

1) 9/19

2) 54 sweets

3) 30 pages

4) Rs. 2.8

5) 21 km

Step-by-step explanation:

Sol. 1 )

=> 11/19 of cup is filled

=> 1 - 11/19 of cup is empty

=> 1 - 11/19 = (19-11)/19 = 8/19

=> 9/19 of the cup is empty

Sol. 2)

=> 72 sweets

=> 1/4 with her

=> 1 - 1/4 = 3/4 shared

=> 3/4 of 72 is the number of sweets shared

=> 3/4 of 72 = (3*72)/4 = 3*18 = 54

=> She gave 54 sweets to her friends

Sol. 3)

=> 3/5 of 75 page of his lesson is read

=> 1 - 3/5 = 2/5 of 75 pages is left

=> 2/5 of 75 = (2*75)/5 = 2*15 = 30

=> 30 pages is left to read

Sol. 4)

=> Rs. 11.20 for 4 gallons of oil

=> Rs. (11.20/4) for 1 gallon of oil

=> 11.20 / 4 = 2.8

=> 1 gallon of oil costs Rs. 2.8

Sol. 5)

=> 48.3 km in 2.3 litres of petrol

=> (48.3/2.3) km will be covered in 1 litre of petrol

=> 21 km will be covered in 1 litre of petrol

Please mark as brainist. Too much of hardwork is deposited in it. Plz
