A Toyota sedan with a 40.5 L petrol tank capacity runs out of petrol. Three containers, each with a capacity of 13.25 L, are used to fill up the tank. How many millilitres (mL) of petrol are still needed to fill the tank to capacity?

Convert to Millilitres: Convert the tank capacity from liters to millilitres. 1 liter = 1,000 millilitres 40.5 L = 40.5 * 1,000 mL Calculation: 40.5 * 1,000 = 40,500 mLCalculate Petrol Amount: Calculate the total amount of petrol that can be put into the tank using the three containers. Each container has a capacity of 13.25 L, which needs to be converted to millilitres. 13.25 L = 13.25 * 1,000 mL Calculation: 13.25 * 1,000 = 13,250 mL per containerTotal Petrol from Containers: Calculate the total amount of petrol provided by the three containers. Total petrol from containers = 3 * 13,250 mL Calculation: 3 * 13,250 = 39,750 mLCalculate Petrol Needed: Subtract the total amount of petrol provided by the containers from the total tank capacity to find out how much more petrol is needed. Petrol needed = Tank capacity - Petrol from containers Calculation: 40,500 mL - 39,750 mL = 750 mL

Q. A Toyota sedan with a

40.5\,\text{L}

petrol tank capacity runs out of petrol. Three containers, each with a capacity of

13.25\,\text{L}

, are used to fill up the tank. How many millilitres

(\text{mL})

of petrol are still needed to fill the tank to capacity?

Convert to Millilitres: Convert the tank capacity from liters to millilitres. $\newline$ $1$ liter $= 1,000$ millilitres $\newline$ $40.5$ L $= 40.5 \times 1,000$ mL $\newline$ Calculation: $40.5 \times 1,000 = 40,500$ mL
Calculate Petrol Amount: Calculate the total amount of petrol that can be put into the tank using the three containers. $\newline$ Each container has a capacity of $13.25\,\text{L}$ , which needs to be converted to millilitres. $\newline$ $13.25\,\text{L} = 13.25 \times 1,000\,\text{mL}$ $\newline$ Calculation: $13.25 \times 1,000 = 13,250\,\text{mL}$ per container
Total Petrol from Containers: Calculate the total amount of petrol provided by the three containers. $\newline$ Total petrol from containers = $3 \times 13,250 \, \text{mL}$ $\newline$ Calculation: $3 \times 13,250 = 39,750 \, \text{mL}$
Calculate Petrol Needed: Subtract the total amount of petrol provided by the containers from the total tank capacity to find out how much more petrol is needed. $\newline$ Petrol needed = Tank capacity - Petrol from containers $\newline$ Calculation: $40,500 \, \text{mL} - 39,750 \, \text{mL} = 750 \, \text{mL}$
