Question

A carpenter has a wooden stick that is 84 centimeters long. She cuts off 25% from the end of

the stick. Then she cuts the remaining stick into 6 equal pieces. What is the length of each
piece?

How did you get 63?

Answer 1

Answer: 10.5 cm

=======================================================

Step-by-step explanation:

25% = 25/100 = 0.25

25% of 84 = 0.25*84 = 21

So 21 cm has been cut off, leaving 84-21 = 63 cm left over

Or you could say that if 25% has been cut off, then 75% of the stick remains

So, 75% of 84 = 0.75*84 = 63 cm remains.

The remaining length of 63 cm is cut into 6 equal pieces

Each smaller piece is 63/6 = 10.5 cm long
