  1. A tank is 3/4 full. It contains 60 litres. What is the full capacity of the tank?

    Answer: 80 litres

    Full capacity = 60 ÷ (3/4) = 60 × (4/3) = 80 litres.

  2. What is the value of 144 ÷ 0.12?

    Answer: 1200

    144 ÷ 0.12 = 144 × (100/12) = 1200.

  3. Three friends share $96 in the ratio 1:3:4. How much does the person with the largest share receive?

    Answer: $48

    Total parts = 8; largest share = 4/8 × $96 = $48.

  4. A rectangle has length 9 cm and width 5 cm. What is the length of its diagonal?

    Answer: √106 cm

    Diagonal = √(9² + 5²) = √(81 + 25) = √106 cm.

  5. If x + y = 20 and x − y = 6, what is the value of x?

    Answer: 13

    Adding the equations: 2x = 26, so x = 13.

  6. How many minutes are in 3.5 hours?

    Answer: 210

    3.5 × 60 = 210 minutes.
