Question

Michelle wanted to make a photo frame for her mother's birthday. She took a long part of wood measuring 242 cm and cut it into equal parts of 21 cm each. What is the number of small pieces of wood obtained? Is there any piece of wood left?

• A. 12 small pieces of wood is obtained, we have no wood left.
• B. 12 small pieces of wood is obtained, we have 11 cm of wood left.
• C. 11 small pieces of wood is obtained, we have no wood left.
• D. 11 small pieces of wood is obtained, we have 11 cm of wood left.

Answer 1

The correct option is D 11 small pieces of wood is obtained, we have 11 cm of wood left.

242 cm long wood is cut into smaller pieces of 21 cm long.

If we divide 242 by 21 then we will get 11 as the quotient, which means that we have 11 pieces of smaller wood of 21 cm length.

But the remainder is not 0. We have a remainder of 11 here which means that 11 cm of wood is left.
