Given:-

• Cost of 1 litre of Petrol = Rs. 78 ½.

To Find:-

• Cost of 5 litres of Petrol.

Converting Mixed Faction → Improper Fraction.

$\boxed{\pink{\sf{\frac{Whole\;Number×Denominator+Numerator}{Denominator}}}}$

$\frac{(78\times 2 )+ 1}{2}$

$\frac{156 + 1}{2}$

$\frac{157 }{2}$

Now, Cost of 5 Litres of Petrol

$\frac{157}{2} \times 5$

$\frac{(157 \times 5)}{2}$

$\frac{785}{2}$
