Question

Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form. Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form.

Answer 1

Common multiplier = 10, Equal simplest forms = 1/2

Explanation:

Ratio 10 / 20 & 30 / 60 have common multiplier 10.

As 10, 20, 30, 60 are all multiples of 10.

These ratios are equal, as 10/20 = 30/60 = 1/2 (their simplest form)
