Question

A student measures the length of the pencil using a broken ruler. The image shows the measurement by the broken ruler. The student made an error and records the length of the pencil as 7 cm. How can this error be removed?​

Answer 1

Answer:

we can measure it by seeing from which number we are measuring from ex. we are measuring from 5 and the length of object goes to ten

now we have subtract result i.e 10 from where we were measuring 5

Hence

10- 5

= 5

so Five( 5) is the answer
