Question

If an oil tin can accommodate $2\frac{1}{2}$ liters of oil, how many such oil tins will be filled by $8$ liters of oil ?

• A. $3\frac{2}{5}$
• B. $3$
• C. $3\frac{1}{5}$
• D. $4$

Answer 1

The correct option is D $4$

Capacity of oil tin $=2\frac{1}{2}$ liter
Oil that needs to be stored $=8$ liter

Number of oil tins $=8÷2\frac{1}{2}$
$=8÷\frac{5}{2}$

$=8\times \frac{2}{5}$

$=\frac{16}{5}$

$=3\frac{1}{5}$

Since we cannot have a rational number of tin cans, we need $4$ oil tins to store $8$ liters of oil.
