Question

(2) If 3% of wire cut from a piece of 15 m long wire, how
much of wire is left?​

Answer 1

Answer:

Wire left =100%-3%=97%

=15*97/100

=3*97/20

=291/20

=14.55m

Answer 2

Answer:

14.55m

Step-by-step explanation:

Wire left=

$15m - (3\% \: of \: 15m) \\ = 15m - ( \frac{3}{100} \times 15m) \\ = 15m - \frac{9}{20} m \\ = \frac{300m - 9m}{20} \\ = \frac{291}{20} m \\ = 14 \frac{11}{20} m \\ = 14.55m$
