Answer 1

Answer:

Step-by-step explanation: 1)  9m = 378rs

                                             so 1m = 378/9 = 42rs

                                 therefore 4m = 42 x 4 = 168rs

4) 8l = 100km

so 1l = 100/8 = 12.5km

therefore 26l = 12.5 x 26 = 325km

5) 5km = 108l

so 1km = 108/5 = 21.6l

therefore 1650km = 21.6 x 1650 = 35640l
