Question

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

Answer 1

1/8
There are 180 cm. in 1.8 m. 180+180+60+60=480. So the perimeter is 480. the ratio would be 60:480, but in lowest terms it is 1:8.

Answer 2

Answer: The required ratio is 1:8

Step-by-step explanation:

Width\breadth of picture = 60 cm

Length of picture = 1.8 m = 180 cm

Let P is the perimeter ,  l is length and b is breadth then  

$P= 2(l+b) = 2( 60+180) = 480$

Now ratio of width to its perimeter is given by

$\dfrac{width}{perimeter} =\dfrac{60}{480} =\dfrac{1}{8}$

Hence, the required ratio is 1:8
