  1. A cinema sells 347 tickets on Friday and 289 tickets on Saturday. How many tickets were sold in total?

    Answer: 636

    347 + 289 = 636 tickets sold over both days.

  2. If pencils cost $0.35 each, how much do 20 pencils cost?

    Answer: $7.00

    20 × $0.35 = $7.00.

  3. A pole 3 feet tall casts a 2-foot shadow. A nearby tower casts an 18-foot shadow. How tall is the tower?

    Answer: 27 ft

    Using proportions: height/shadow = 3/2, so tower height = (3/2) × 18 = 27 ft.

  4. What is the total cost of 3 shirts at $15 each and 2 pairs of pants at $25 each?

    Answer: $95

    3 × $15 = $45, 2 × $25 = $50, total = $95.

  5. A school has 480 students. 5/8 of them are girls. How many boys are there?

    Answer: 180

    Girls = 5/8 × 480 = 300, so boys = 480 − 300 = 180.

  6. A tank holds 500 liters. If it is 40% full, how many more liters are needed to fill it completely?

    Answer: 300 liters

    The tank has 40% × 500 = 200 liters, so 300 more liters are needed.
