Answer 1

3rd answer is correct

Explanation:

• Total liters of oil that Hannah has : 4 l
• Amount of liters she has used : 1 1/2
• Amount of oil that is left in the bottle :

`\text{oil \: left \:in \: the \: bottle = total \: amount \: of \: oil \: - \: amout \: of \: oil \: alreday \: used } \\ \text{oil \: left \:in \: the \: bottle = } {4 - 1 (1)/(2) } \\ \text{oil \: left \:in \: the \: bottle = } 4 - (3)/(2) \\ \text{oil \: left \:in \: the \: bottle = } (4 * 2)/(1 * 2) - (3)/(2) \\ \text{oil \: left \:in \: the \: bottle = } (8)/(2) - (3)/(2) \\ \text{oil \: left \:in \: the \: bottle = } (5)/(2) \\ \text{oil \: left \:in \: the \: bottle = }2(1)/(2)`
