Question

the ratio of the numbers of kilometres travelled by a car to the number of litres of petrol consumed is 16:2. if the car travels 40 km,how much petrol will it consumed?​

Answer 1

Answer:

16:2::40:x. 16x=2×40 =16x=80 ,x=80/16 ,x=5. 5 litres of petrol

Answer 2

Answer:

5 liters petrol

Step-by-step explanation:

the ratio of km to litre is 16:2 if we assume it as 16/2 we will get 8/1 that is 8:1 means I litre petrol for every 8 kilometers.

according to this ratio if we assume this as fraction (8/1) we can make the numerator as 40. for this we will need to multiply 8 as well as 1 by 5.

after doing this we will get new fraction as 40/5 which means 40:5. according to this for 40 km it will use 5 litres of petrol.
