Question

subtract 18/215 ml from 21l​

Answer 1

Solution :-

we know that,

• 1 litre = 1000 ml

so,

→ 21 litre = 21 * 1000 = 21000 ml .

now,

→ 21 litre - (18/215) ml

→ 21000 ml - (18/215) ml

→ (21000 * 215 - 18)/215

→ (4514982/215) ml

if you want to change into litre divide it by 1000 now

→ (4514982/215) * (1/1000)

→ 20.999 litre (Approx) (Ans.)

To find:

Subtraction

Solution:

subtract 18/215 ml from 21l

Converting milliliters to liters

To convert milliliters to liters, just divide the given fraction by 1000.

$\dfrac{18}{215} \div 1000$

$= > \dfrac{18}{215} \times \dfrac{1}{1000}$

$= > \dfrac{18}{215000}$

Now, subtract:

$21 - \dfrac{18}{215000}$

$= > \dfrac{4515000 - 18}{215000}$

$= > \dfrac{4514982}{2150000}$

$= > 20.999$

Hence, the required answer is 20.999 liters.
