-18/8

= -9/4

= - 2.25

Oops i thought it was |x+8| = -3

No solution.

An absolute value of a number will never be negative.

Whole number part remains unchanged.

2 3/5 = 2 + 3 ÷ 5 = 2 + 30 ÷ 5 ÷ 10 = 2 + 6 ÷ 10 = 2.6

f divided by 3

= $\dfrac{f}{3}$

It is not going to move - 30 degrees...... Thats anticlockwise......

Amendment by myself: The hour hand of a clock moves 30 degrees, How many degrees does it moves in 2 1/5 hours?

2 1/5 x 30

= 66 degrees.

Explanation for the answer:

$\sqrt{64\times 81}\\ =\sqrt{64}\times \sqrt{81}\text{(Property of square root)}\\ = 8 \times 9\\ = 72.$

$\dfrac{2}{3} \div \dfrac{1}{2}\\ = \dfrac{2}{3} \times\dfrac{2}{1}\\ =\dfrac{2\times 2}{3}\\ =\dfrac{4}{3}\\ \text{OR}\\ =1\dfrac{1}{3}$

n + 8 is the most simplified form.

When n = 1

n + 8 = 1 + 8 = 9

When n = 2

n + 8 = 2 + 8 = 10.

Like this.

When n = 10000000000,  n + 8 = 10000000008 LOL

This equation is linear.
