Question

In a jar of sweets, 9/13 of the sweets are mints. The rest are toffees. What is the ratio of the number of toffees to the number of mints?

Options

  • A.9 : 4
  • B.4 : 9
  • C.9 : 13
  • D.4 : 13
  • E.13 : 9

Correct answer

B.4 : 9

Explanation

Step 1: Find the fraction of toffees

Mints = 9/13 of all sweets.

Toffees = 1 − 9/13 = 13/13 − 9/13 = 4/13

Step 2: Write the ratio

Toffees : Mints = 4/13 : 9/13

Since both fractions have the same denominator, just compare the numerators:

Toffees : Mints = 4 : 9

Check: 4 + 9 = 13, and mints are 9/13 of 13 = 9 ✓

Answer: Toffees : Mints = 4 : 9

Question 2 · Multiple choice

Question

A fruit shop has 516 kilograms of apples and 372 kilograms of pears. If the weight of the fruit in each box is 12 kilograms, then how many more boxes of apples than pears does the shop have?

Options

  • A.43
  • B.31
  • C.74
  • D.24
  • E.12

Correct answer

E.12

Explanation

Step 1: Find the number of apple boxes

Apple boxes = 516 ÷ 12 = 43 boxes

Step 2: Find the number of pear boxes

Pear boxes = 372 ÷ 12 = 31 boxes

Step 3: Find the difference

Extra apple boxes = 43 − 31 = 12 more apple boxes

Check: 43 × 12 = 516 ✓ and 31 × 12 = 372 ✓

Answer: There are 12 more boxes of apples
