Question

. A picture is 60cm wide and 1.8m long. The ratio of its width to its perimeter in lowest form is

Answer 1

Answer:

Length of Picture = 1.8 m = 180 cm

Width of picture = 60 cm

Perimeter of picture = 2(l+b)=2(180+60)=480 cm

ratio of width to perimeter = 60 / 480 = 1 / 8

Hence The ratio of its width to its perimeter in lowest form is 1:8.
