Question

1student added 1/4+1/5+1/2 and got 19/20 and which is less than 1.how will you justify this?​

Answer 1

Students justified $19 < 20$ is less than 1.

Step-by-step explanation:

We have,

$\frac{1}{4} +\frac{1}{5}+\frac{1}{12}$

LCM of 4, 5 and 2 = 20

=$\frac{5 + 4 +10}{20}$

=$\frac{19}{20}$

If the numerator is less than denominator, then the fraction is less than 1.

$=\frac{19}{20}, 19 < 20$, is less than 1.
