Question

Roma gave a wooden board of length 150 ¼ cm to a carpenter for making a shelf. The carpenter sawed off a piece of 40 1/5 cm from it. What is the length of the remaining piece?​

Answer 1

Answer: 110.05 cm

Step-by-step explanation:

150 ¼ - 40 1/5

= $\frac{601}{4}$ - $\frac{201}{5}$

Since the LCM of 4 and 5 = 20

$\frac{601}{4}$ x $\frac{5}{5}$ - $\frac{201}{5}$ x $\frac{4}{4}$

= $\frac{3005}{20}$ - $\frac{804}{20}$

= $\frac{3005 - 804}{20}$

= $\frac{2201}{20}$

= 110.05 cm
