उत्तर
Converting the given fractions into like fractions.
LCM of the denominators of `1/6` and `1/2`
| 2 | 6, 2 |
| 3 | 3, 1 |
| 1, 1 |
∴ LCM of 6 and 2 = 2 × 3 = 6
Now, we convert the given fractions into equivalent fractions with denominator 6.
So, `(1 xx 1)/(6 xx 1) = 1/6` and `1/2 = (1 xx 3)/(2 xx 3) = 3/6`
∴ `1/2 - 1/6 = 3/6 - 1/6`
= `(3 - 1)/6`
= `(3 ÷ 2)/(6 ÷ 2)` ...`[(because "For reducing a fraction to its lowest terms, we divide"),("its numerator and denominator by their HCF")]`
= `1/3`
