Question

¼ litre of milk cost Rs 4. How much would 6¹/2 It of milk cost?​

Answer 1

SOLUTION :

Given that,

Cost of 1/4 L milk = Rs. 4

TO FIND :

$cost \: of \: 6 \frac{1}{2} \: milk$

PROCESS :

Let us solve this word problem by a method called the unitary method

Cost of 1 L milk will be =

$4 \div \frac{1}{4}$

$4 \times 4$

$16$

Now,

Now, let us convert the mixed fraction.

$6 \frac{1}{2} = \frac{13}{2}$

So,

Cost of 13/2 litres milk =

$\frac{13}{2} \times 16$

$13 \times 8$

$104$

Hence, the required cost is 104
