Question

Find the ratio of 3km to 300m

Answer 1

10 : 1 is the ratio is 3km to 300m.

3km = 3000m.
therefore, 3000:300
= 10:1 .

Answer 2

Answer:

Required ratio is 10:1

Step-by-step explanation:

Here we want to find ratio of 3km to 300 m.

For finding ratio first we need to know about ratio.

If x and y are two numbers then their ratio is x:y.

By some example we can understand this concept easily.

Example -1:

Ratio of 8 and 4

$= 8:4 = \frac{8}{4} = \frac{2 \times 2 \times 2}{2 \times 2} = \frac{2}{1} = 2:1$

Example -2:

Ratio of 25 and 35

$= 25:35 = \frac{25}{35} = \frac{5 \times 5}{5 \times 7} = \frac{5}{7} = 5:7$

Example -3:

Ratio of 100 and 175

$=100:175 = \frac{100}{175} = \frac{2 \times 2 \times 5 \times 5}{5 \times 5 \times 7} = \frac{2 \times 2}{7} = \frac{4}{7} = 4:7$

Here two numbers are 3 km and 300 m.

But first need to convert these quantity in same unit.

We know, 1 km = 1000 m

So 3 km = (3×1000) m=3000 m

Ratio of 3000 m and 300 m is

$3000:300 = \frac{3000}{300} = \frac{10}{1} = 10:1$
