Algebra find the missing value in the equation 3/12+1/12+? /12=1/2 so what is it?

It would be 2/12ths. Work : 1/2 = 6/12, 6/12 - (3/12 + 1/12) = 2/12.

The missing number is 2/12 because 3+1+2=6 and 6/12 is equal to 1/2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
