उत्तर
This statement is False.
Explanation:
Here, `(-3)/4` and –2 (Like)
First, we do same denominator.
We get, `- 3/4` and `(-2 xx 4)/(1 xx 4)`
⇒ `(-3)/4` and `(-8)/4`
Now, comparing both numbers,
`(-3)/4 > (-8)/4`
⇒ `(-3)/4 > -2`
So, `- 3/4` is greater than –2.

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`
