Question

Find the ratio between 4 km and 20 m.

Answer 1

Answer:

The ratio between 4km and 20 m is 200 : 1

Step-by-step explanation:

When we find the ratio, first we should check the units of measurements. They must be the same.

Here one quantity is given in kilometers and the other quantity in meters.

So to convert kilometers to meters, it is enough to multiply the number by 1000. Because

$1\ km=1000m$

So,

$4 \ km =4\times 1000=4000m$

Now we have two quantities in the same unit, which are 4000m and 20 m. Hence the ratio is,

$4000:20$

Removing the common factor we obtain the ratio as

$200:1$
