A piece of wire $\dfrac{7}{8}$ meter long broke into two pieces. One piece was $\dfrac{1}{4}$ meter long. How long is the other piece?


Use "/" to separate numerator and denominator.

The correct answer is 5/8

Total length of wire = $\dfrac{7}{8}$ meter

Length of one piece of wire = $\dfrac{1}{4}$ meter


Length of other piece of wire = Length of the original wire minus this one piece of wire


= $\dfrac{7}{8}$ – $\dfrac{1}{4}$


= $\dfrac{7}{8}$ – $\dfrac{1 \times 2}{4 \times 2}$


= $\dfrac{7}{8}$ – $\dfrac{2}{8}$


= $\dfrac{5}{8}$


∴ Length of the other piece of wire = $\dfrac{5}{8}$ meter
