Question

John bought 27.5 m of cloth. How many cm of cloth did he buy? ( A ) 275 cm ( B ) 2750 cm ( C ) None of these ( D ) 27500 cm

Answer 1

Given - Measurement of cloth

Find - Measurement in centimetres

Solution - He bought ( B ) 2750 centimetres of cloth.

As per the fact, 1 metre is equal to 100 centimetres.

The amount of cloth John has = 27.5 metres or 275/10 metres.

Comparing the given information, we get -

1 metre = 100 centimetres

So, the equivalent of 275/10 metres = 100*275/10

Performing multiplication and division -

Equivalent in centimetres = 2750 centimetres.

Thus, John bought ( B ) 2750 centimetres of cloth.

Answer 2

John bought 2750 cm of cloth.

The correct answer is the option (B).

-----------------------------------------------------------------------------------------

Let's understand a few concepts:

The conversion rate from meter to centimeter is given as follows:

$\boxed{\bold{1 \:meter = 100 \:centimeter}}$

-----------------------------------------------------------------------------------------------

Let's solve the given problem:

The length of the cloth bought by John = 27.5 m

Here we are asked to give the length of the cloth bought by John in centimeters, so we will use the above-mentioned conversion rate to convert 27.5 meters into centimeters.

Therefore,

The length of the cloth John bought in centimeters is,

= (27.5 meter) × (100 centimeter per meter)

= 27.5 × 100 centimeter

= 2750 centimeter

Thus, John bought 2750 cm of cloth.
