1/10*344
=344/10
=34.4
We will move the decimal to the left side in case of division.
Suppose that 2,4166666 is just 2,416. So the fraction will be 2 in front of a fraction 416 (in nominator) and 1000 ( in denominator) I hooope you understood
Angle 1 is equal to the sum of angle 2 and 3. There is a special name for it but I can't think of it right now :/ .. but anyways , it would be 34 + 76 = 110
