Question

Express as km using decimals 8888m.

Answer 1

Hint: We will use the conversion table of units.
We know that,
In 1 Km there is 1000m.
It can be written as: 1000 m = 1 Km -- (A)

Complete step-by-step answer:
Step 1: Find the value of 1 m in Km by dividing 1000 both sides in (A)
Therefore, $1{\text{m}} = \dfrac{1}{{1000}}{\text{Km}}$-- (B)
Step 2: Now we have to find the value of 8888m in Km, Therefore multiply by 8888 on both sides in (B)
$ \Rightarrow 8888{\text{m}} = \dfrac{1}{{1000}} \times 8888$ Km
Step 3: Now count the number of zeros 1000 have, Its 3.
From left move to right by counting digits one by one in 8888, then put the decimal after 3 digits.
$ \Rightarrow 8888{\text{m}} = 8.888{\text{Km}}$
Therefore, the answer is 8.888 Km.

Additional Information: The Conversion table is very important to remember in unit conversion. Without this you can’t be able to attempt such types of questions.
The conversion table is like:

KILO

HECTO

DECA

[ UNIT ]

DECI

CENTI

MILLI

Unit - Meter/Litre/Grams.
From unit to moving left Unit will become larger and while moving right unit will become smaller.
From moving left to right multiply by 10 for each column and while moving right to left divide by 10 for each column.
For example:
1 KILO Unit = 10 Hecto
1 KILO Unit = 10 x 10 = 100 Deca
1 KILO Unit = 10 X 10 X 10 = 1000 Unit and so on.
1 CENTI Unit = $\dfrac{1}{10}$ Deci
1 CENTI Unit = $\dfrac{1}{100}$ Unit and so on.
Note: While this type of conversion problems always remember the conversion table first. Then in which unit you want to convert, place it into the right side and which unit you gave in question to convert. Place it on the left side. Then always find for the value of 1 unit first. Then multiply both sides by the number which you want to express on both sides.
