1/2 = fraction. 1.2= decimal 12%= percent
Simplify \frac{5}{3}x35x to \frac{5x}{3}35x
x-\frac{5x}{3}<3x−35x<3
2
Simplify x-\frac{5x}{3}x−35x to -\frac{2x}{3}−32x
-\frac{2x}{3}<3−32x<3
3
Multiply both sides by 33
-2x<3\times 3−2x<3×3
4
Simplify 3\times 33×3 to 99
-2x<9−2x<9
5
Divide both sides by -2−2
x>-\frac{9}{2}x>−29
Solutions
1hr = 60 min
180 ÷ 60 = 3

To return back to -18°C from -10°C, you would have to lower the temperature by -8°C to compensate for the difference.
Hope that helps!
