Question

Carmen has three blocks of chocolate that are identical.

She also has a 4th smaller block of chocolate that weighs 175 grams.

Carmen has 1480 grams of chocolate in total.

Which expression can be used to calculate the mass of one of the large blocks of chocolate?

Worked Solution

Mass of the 3 larger blocks

= 1480 − 175

∴\therefore Mass of one larger block

= (1480 − 175) ÷ 3

Question

Stuart has three bottles of soft drink that are identical.

He also has a 4th smaller bottle of soft drink that contains 375 millilitres.

Stuart has 4125 millilitres of soft drink in total.

Which expression can be used to calculate the volume of one of the large bottles of soft drink?

Worked Solution

Total volume of the 3 larger bottles

= 4125 − 375

Question

Akira has five trucks that hold identical quantities of garden soil.

He also has a 6th smaller truck that holds 4 cubic metres of garden soil.

Akira's six trucks hold 59 cubic metres of garden soil in total.

Which expression can be used to calculate the number of cubic metres of garden soil one of the large truck holds?

Worked Solution

Cubic metres in the 5 larger trucks

= 59 − 4
