Question

a piece of rod 2/1/4m long broke into two piece. one piece is 1/1/2m long. how long is the other piece?

​

Answer 1

The length of the second part is $\frac{3}{4}\ m$.

Step-by-step explanation:

The total length of the rod is, L = $2\frac{1}{4}=\frac{9}{4}$ m.

The length of the first part is, l₁ = $1\frac{1}{2}=\frac{3}{2}$ m.

Compute the length of the second part as follows:

l₂ = L - l₁

  $=\frac{9}{4}-\frac{3}{2}$

  $=\frac{9-6}{4}$

  $=\frac{3}{4}$

Thus, the length of the second part is $\frac{3}{4}\ m$.
