45% of 224×?% of 120=8104.32

If $$ {1\over3} ({12x\over5}-{1\over2})+{6\over5}={7\over6}$$ then what is the value of x?

The value of 24 ÷ 4 ×(3 +3) ÷2 is:

5-[4-{3-(3-3-6)}] is equal to:

Assume that
$$\sqrt{3} = 3.605 \ (approximately)  $$
$$\sqrt{130} = 11.40 \ (approximately)  $$
Find the value of
$$\sqrt{1.3} + \sqrt{1300}+\sqrt{0.013}  $$

$$ { \sqrt{(0.798)^2+0.404×0.798+(0.202)^2}+1=?} $$

Simplify : $$\sqrt{[(12.1)^2-(8.1)^2]÷[(0.25)^2+(0.25)(19.95)]} $$

Find the value of   $$ {(0.75)^3\over1-.75}+[0.75+(0.75)^2+1]$$
