Question

a gas cylinder contains 35 litres of gas 23 3/5 litres of gas is used how much gas is left in the cylinder​

Answer 1

Step-by-step explanation:

35 litre = 175/5 litre

23 3/5 litre = 118/5 litre

number of gas used = 118/5 litre

gas left = ( 175/5) (118 /5) = 57/5 litre

57/5 litre = 11 2/5 litre

Answer 2

The amount of gas left in gas cylinder = $11\frac{2}{5}$ liters.

Given:

A gas cylinder contains 35 litres of gas

$23 \frac{3}{5}$ liters of gas is used

To find:

The remaining gas after using $23 \frac{3}{5}$ liters of gas

Solution:

From given data a gas cylinder contains 35 liters of gas and

$23 \frac{3}{5}$ liters of gas is used  

⇒ if we convert $23 \frac{3}{5}$ into a improper fraction then

$23 \frac{3}{5}$ = $\frac{118}{5}$ liters    [ ∵ 118 = (5 × 23) +3 ]  

⇒ From the gas  cylinder $\frac{118}{5}$ liters of gas is used

Remaining gas in cylinder = 35 liters -  $\frac{118}{5}$ liters = $\frac{175 - 118}{5}$ = $\frac{57}{5}$ liters

Here,  $\frac{57}{5}$ can be convert as $11\frac{2}{5}$ liters  [ ∵ 57 = (11×5) + 2 ]

Therefore, the amount of gas left in gas cylinder = $11\frac{2}{5}$ liters.
