Question

160cm : 20m =

25:2
2: 25
16: 2
8 : 1

Answer 1

2 : 25 is the answer

Answer 2

Step-by-step explanation:

convert 20 m into cm .

that is, 2000 cm

so the ratio would be 160cm:2000cm

Convert ratio into fraction.

160cm/2000cm

Cm and cm would cancel each other since they are in fraction.

Left with 160 and 2000 as numerator and denominator.

0 and 0 cancel each other.

so 16/200 is current fraction.

divide 16 and 200 by a common number. I divide it by 4

Now it is 4/50

again divide it by common no 2

finally it is 2/25

convert this fraction into ratio

it would be 2:25

so correct option is b.
