Question

Mrs. Tillman builds furniture. She saws a maple board that is 4.56 meters long into 4 equal lengths. She saws an oak board that is 3.69 meters long into 3 equal lengths. Which is longer, a piece of oak or a piece of maple?

Answer 1

Answer:

A piece of oak is longer than a piece of maple

Explanation:

1- For the maple:

We know that the total length of the maple is 4.56 meters and that this length is equally divided into 4 pieces

Therefore:

Length of each maple piece = $\frac{4.56}{4}=1.14$ meters

2- For the oak:

We know that the total length of the oak is 3.69 meters and that this length is equally divided into 3 pieces

Therefore:

Length of each oak piece = $\frac{3.69}{3}=1.23$ meters

3- Comparing the length of the pieces:

We now calculated that:

length of maple piece is 1.14 meters

length of oak piece is 1.23 meters

We can compare the two values using the number in the tenth position

Therefore:

1.23 > 1.24

which means that one piece of oak is longer than one piece of maple

Hope this helps :)
