Question

find the third proportional of 2m40cm and 40cm ​

Answer 1

Answer:

We know that,

1 m = 100 cm

Here,

2 m 40 cm = 2 m + 40 cm

= ( 2 × 100 + 40 ) cm

= ( 200 + 40 ) cm

= 240 cm

Now ,

Let ,

The third proportion = x

•°• 240 : 40 = 40 : x

=> 240 x = 40 × 40

=> 240 x = 1600

=> x = 1600/240

=> x = 6.66

•°• The third proportion is 6.66 cm = 6 m 66 cm
