Question

Decrease 5 1/4 m by 50 cm. Answer has to be m.

Answer 1

5 1/4 m is 5.25m. 50cm is 0.5m.
So 5.25 - 0.5 = 4.75m, or 4 3/4 m as a fraction

Answer 2

Answer:

$4\frac{3}{4}$ m

Step-by-step explanation:

1 meter = 100 centimeters

50 cm = $\frac{50}{100} m$

50 cm = $\frac{1}{2} m$

Original length = $5\frac{1}{4}=\frac{21}{4} m$

Decrease the original length by 50 cm

So, Length =  $\frac{21}{4} -\frac{1}{2}$

                 =  $\frac{21-2}{4}$

                 =  $\frac{19}{4}$

                 =  $4\frac{3}{4}$

Hence new length is $4\frac{3}{4}$ m
