Decimals are simply a way to express numbers. There is nothing to solve!
extended form of decimals
expanded form for the decimals 1.203 = 1 + 0.2 + 0.003
Not necessarily, but often it is simpler to convert fractions into decimals to solve the equation.
A full turn is 360° which is equivalent to 2π radians To convert form degrees to radians divided by 360° and multiply by 2π; however 360° = 180°×2, therefore divide by 180° and multiply by π radians. → 75° = 75° ÷ 180° × π radians = 5π/12 radians ≈ 1.31 radians

The LCM refers to whole numbers, not decimals.
First, get the 12 degrees and 28 minutes into decimal form by adding 28/60 to 12, obtaining 12.46667 degrees. Then multiply by pi / 180 to convert to radians, obtaining 0.2175844 radians.
