Question

17. A piece of wire is of length 15 1/2cm. If a piece of 3 1/5cm length is cut
from it, what is the length of wire left?​

Answer 1

Answer:

length of wire = 15.5 cm

length of cut = 3.2 cm

remaining wire = 15.5 - 3.2 = 12.3 cm

Answer 2

12 whole 3/10

Step-by-step explanation:

Total length of piece of wire = 15 ½cm

Length of first piece cut = 3 ⅕

Length of wire left =

$15 \frac{1}{2} - 3 \frac{1}{5}$

$\frac{31}{2} - \frac{16}{5}$

LCM = 10

$\frac{155 - 32}{10}$

$= \frac{123}{10}$

$= 12 \frac{3}{10}$
