उत्तर
Given numbers are `1/4, 13/16` and `5/8`.
First, we convert the number as like denominator.
| 2 | 4, 16, 8 |
| 2 | 2, 8, 4 |
| 2 | 1, 4, 2 |
| 2 | 1, 2, 1 |
| 1, 1, 1 |
Taking LCM of 4, 16, 8 = 2 × 2 × 2 × 2 = 16
Now, `1/4 = 1/4 xx 4/4 = 4/16`,
`5/8 = 5/8 xx 2/2 = 10/16`
`13/16 > 10/16 > 4/16`
i.e. `13/16 > 5/8 > 1/4`

The number `sqrt2` is shown on a number line. Steps are given to show `sqrt3` on the number line using `sqrt2`. Fill in the boxes properly and complete the activity.
Activity :
- The point Q on the number line shows the number ______.
- A line perpendicular to the number line is drawn through the point Q. Point R is at unit distance from Q on the line.
- Right angled ∆ORQ is obtained by drawing seg OR.
`l ("OQ") = sqrt2` , `l("QR") = 1`
`therefore` by Pythagoras theorem,
`[l("OR")]^2 = [l("OQ")]^2 + [l("QR")]^2 `
= `square^2`+ `square^2` = `square` + `square`
= `square`
∴ l(OR) = `square`
Draw an arc with centre O and radius OR. Mark the point of intersection of the line and the arc as C. The point C shows the number `sqrt3`.
