Aneli [31]

To find the value of 0.080 cm in meter we are using unitary method

We know that

100 cm =1 m

1 cm =\frac{1}{100} m

Therefore, 0.080 cm =\frac{1}{100}\times 0.080 m

0.080 cm =\frac{1}{100}\times \frac{80}{1000}m

0.080 cm =\frac{8}{10000}m

0.08cm=0.0008 m

Hence, the value of 0.080 cm is equal to 0.0008 meter .
