A vehicle uses 856.7 liters of
petrol to travel 1000 kilometers. How many liters of petrol will be
used on a journey of 100 kilometers?

We know that the vehicle uses 856.7
liters of petrol to travel 1000 kilometers. We’re asked to work out how many
liters of petrol will be used on a journey of 100 kilometers. 100 is 10 times smaller than
1000. 1000 divided by 10 is 100. So, to find out how many liters of
petrol the vehicle will use in a journey of 100 kilometers, we can divide 856.7 by
10.

To divide 856.7 by 10, we need to
shift the decimal place one place to the left. 856.7 divided by 10 equals
85.67. If a vehicle uses 856.7 liters of
petrol to travel 1000 kilometers, it will use 85.67 liters of petrol on a journey of
100 kilometers. 856.7 divided by 10 is 85.67
liters.
