Question

Write the ratios of second quantity to first quantity in the reduced form: 5 dozen pens, 120 pens

Answer 1

5 dozen pens= 5*12= 60

ratio:

$\frac{120}{60}$

or simplified

$\frac{2}{1}$

Answer 2

1 dozen pens = 12 pens

therefore 5 dozen pens = 5 x 12

= 60 pens

therefore 120/60 = 2/1 = 2: 1

so the ratio of the second quantity to the first is 2: 1
