Question

A petrol tank is filled with 4, 1/4 litres of petrol. If 1/8 of the petrol leaks out, then how many litres of petrol would be left? with statement please​

Answer 1

Given:- A petrol tank is filled with 4 1/2 litres of petrol and 1/8 of it leaks out.

To find:- how many litres of petrol would be left after leakage.

Solution :-

$\sf \to \: 4 \dfrac{1}{4} = \dfrac{17}{4}$

Let the remaining petrol be x litres.

Now, according to question,

Statement will be,

Remaining petrol = Total amount petrol in tank - amount of leaked petrol

$\sf \implies \: x = \dfrac{17}{4} - \dfrac{1}{8} \\ \\ \sf \implies x = \frac{17 \times 8 - 4 \times 1}{32} \\ \\ \sf \implies \: x = \dfrac{136 - 4}{32} \\ \\ \sf \: \implies \: x = \frac{132}{32} \\ \\ \implies \boxed{\boxed{ \purple{ \bf{x = 4.1 \: litres}}}}$

∴ 4.1 litres of petrol would be left in the tank.

Answer 2

Step-by-step explanation:

Given that, a petrol tank is filled with 4. 1/4 litres of petrol. If 1/8 of the petrol leaks out.

We have to find that how many litres of petrol would be left.

Say that the x litre of petrol left in the tank.

Total petrol = 4 1/4 = 17/4

Leaked petrol = 1/8

Total petrol = Leaked petrol + Left petrol

Substitute the values,

→ 17/4 = 1/8 + x

→ 17/4 - 1/8 = x

→ (34 - 1)/8 = x

→ 33/8 = x

Hence, the 33/8 litres of petrol left in the tank.

Verification

From above calculations we have x is 33/8

Substitute value of x in 17/4 = 1/8 + x

→ 17/4 = 1/8 + 33/8

→ 17/4 = 34/8

→ 17/4 = 17/4
