Question

A deer tick measures 29 centimeters in length in a photograph. If the photo has been enlarged by a factor of 100, what is the actual length of the deer tick?

Answer 1

we know that

[length in a photograph]/[the actual length]=[factor of scale]

[the actual length]=[length in a photograph]/[factor of scale]
[factor of scale]=100
so
[the actual length of the deer tick]=29/100---------> 0.29 cm

the answer is 0.29 cm
