0.27 ÷ 0.03 = explain each and every step in this process

0.27 divided by 0.03 = 9

think of it this way it's like doing it 27 divided by 3 which is = 9

but then u see
9x3=27
9x0.3=2.7

so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.

Ais the correct one

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
