Answer:
[tex]3.\ \dfrac{3x}{11x}, \dfrac{6}{22}, \dfrac{9}{33},\dfrac{12}{44}[/tex]
[tex]4. -18\\5.\ 400[/tex]
Step-by-step explanation:
Solution 3:
Equivalent fractions to are to [tex]\frac{3}{11}[/tex] be found out.
Method: By Multiplying both the denominator and numerator with the same number, we can easily find equivalent fractions.
1. Multiply with 2:
[tex]\dfrac{3 \times 2}{11 \times 2}\\\Rightarrow \dfrac{6}{22}[/tex]
2. Multiply with 3:
[tex]\dfrac{3 \times 3}{11 \times 3}\\\Rightarrow \dfrac{9}{33}[/tex]
3. Multiply with 4:
[tex]\dfrac{3 \times 4}{11 \times 4}\\\Rightarrow \dfrac{12}{44}[/tex]
If we try to write in variable form, it can be written as:
[tex]\dfrac{3x}{11x}[/tex]
where x is any number.

Solution 4:
[tex](2x-10)[/tex] when [tex]x=-4[/tex]
[tex]2 \times (-4) -10\\\Rightarrow -8 -10\\\Rightarrow -18[/tex]
------------
Solution 5:
[tex](10a)^2, a=-2\\\Rightarrow \{10 \times (-2)\}^2\\\Rightarrow (-20)^2\\\Rightarrow 400[/tex]
