Which is bigger 0.5 or 0.50

They are the same
You can write 0.50 as 0.5 because the 0 at the end doesn't really mean anything xxx hope it helps x

0.5 AND 0.50 ARE THE SAME THING . YOU CAN WRITE IT  EITHER WAY BECAUSE THE  ZERO AT THE END DOESN'T REALLY MEAN ANYTHING. THEY ARE EQUALS

Here, feel free to ask if there are any questions
