Answer:
[tex]4\frac{3}{4}[/tex] m
Step-by-step explanation:
1 meter = 100 centimeters
50 cm = [tex]\frac{50}{100} m[/tex]
50 cm = [tex]\frac{1}{2} m[/tex]
Original length = [tex]5\frac{1}{4}=\frac{21}{4} m[/tex]
Decrease the original length by 50 cm
So, Length = [tex]\frac{21}{4} -\frac{1}{2}[/tex]
= [tex]\frac{21-2}{4}[/tex]
= [tex]\frac{19}{4}[/tex]
= [tex]4\frac{3}{4}[/tex]
Hence new length is [tex]4\frac{3}{4}[/tex] m
