Answer:

$3.\ (3x)/(11x), (6)/(22), (9)/(33),(12)/(44)$

$4. -18\\5.\ 400$

Explanation:

Solution 3:

Equivalent fractions to are to
(3)/(11) 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:

$(3 * 2)/(11 * 2)\\\Rightarrow (6)/(22)$

2. Multiply with 3:

$(3 * 3)/(11 * 3)\\\Rightarrow (9)/(33)$

3. Multiply with 4:

$(3 * 4)/(11 * 4)\\\Rightarrow (12)/(44)$

If we try to write in variable form, it can be written as:

(3x)/(11x)

where x is any number.

---------------

Solution 4:

(2x-10) when
x=-4

$2 * (-4) -10\\\Rightarrow -8 -10\\\Rightarrow -18$

------------

Solution 5:

$(10a)^2, a=-2\\\Rightarrow \{10 * (-2)\}^2\\\Rightarrow (-20)^2\\\Rightarrow 400$
