Square OABC is drawn on a centimetre grid. O is (1,3) A is (3,3) B is (3,5) C is (1,5)

Write down how many invariant points there are on the perimeter of the square when

OABC is rotated 90’ clockwise, centre (3,3)

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
