Answer 1

$\large\sf\underline{Question\:1:-}$

The product of a rational number and its reciprocal is ______ ?

‎

$\large\sf\underline{Answer:-}$

The product of a rational number and its reciprocal is ${\sf{{\pink{1}}}}$.

• Let's take an example,

Rational number = $\sf\:\frac{3}{2}$

Its reciprocal = $\sf\:\frac{2}{3}$

So their Product

$\sf⟹\:\frac{3}{2}×\frac{2}{3}$

$\sf⟹\:\frac{6}{6}$

$\sf⟹\:1$

$\dag\:\underline{\sf [Hence\: Verified]\::}$

$\large\sf\underline{Question\:2:-}$

• $\sf\:Add\::\frac{2}{3}+\frac{3}{2}$

‎

$\large\sf\underline{Answer:-}$

$\sf⟹\:\frac{2}{3}+\frac{3}{2}$

• Let's find LCM of 3 and 2

$\sf⟹\:\frac{(2×2)+(3×3)}{6}$

$\sf⟹\:\frac{4+9}{6}$

$\sf⟹\:\frac{13}{6}$

• Reducing it into decimal

${\sf{{\pink{⟹\:2.166}}}}$

$\large\sf\underline{Question\:3:-}$

• $\sf\:Multiply\::\frac{-6}{5} ×\frac{9}{11}$

‎

$\large\sf\underline{Answer:-}$

$\sf⟹\:\frac{-6}{5} ×\frac{9}{11}$

$\sf⟹\:\frac{-54}{55}$

• Reducing it into decimal

${\sf{{\pink{⟹\:-.098}}}}$

!! Hope it helps !!

Answer 2

Answer:

1. The product of rational number with its. reciprocal is always equal to 1.

2. LCM = 3×2=6

2/3×6= 2×2=4

3/2×6= 3×3=9

4+9/6=13/6

3. -6×9=-54

5×11=55

-54/55

I hope it helps you!
