Question

Which of the following statements correctly applies the cross product rule?

Options

• `1/4` = `4/16` because 1 × 4 = 4 × 1

• `1/4` = `4/16` because 1 × 16 = 4 × 4

• `1/4` ≠ `4/16` because 1 + 16 ≠ 4 + 4

• `1/4` = `4/16` because 1 + 4 = 4 + 1

Answer 1

`1/4` = `4/16` because 1 × 16 = 4 × 4

Explanation:

The cross product rule states: a × d = c × b.

Here, 1 × 16 = 16 and 4 × 4 = 16, so the fractions are equivalent.
