Question

Technician a says that one revolution of the micrometer thimble equals 1/40 inch. Technician b says that on revolution of the thimble equals 0.025 inch. Who is correct

Answer 1

we know that

`0.025=0.025*(1,000)/(1,000)=(25)/(1000)`

Divide by 25 both numerator and denominator

`(25)/(1000)=(1)/(40)`

so

`0.025=(1)/(40)`

therefore

the answer is

Both technicians are correct.
