8and 21 over 40 in decimal and by step pl u ill rate it

There is a simple and easy method through which 8,21/40 can be changed into a decimal. First, divide 21 by 41. Due to the fact that 40 cannot go into 21, you will have to add a decimal, so you are left with 21.0. Next, you have to consider, how many times can 40 go into 210 or 21.0. The answer is 5. Next, multiply 40 by 5 to get the answer of 200. following this, subtract 200 from 210, which means you have ten left over. You then need to add another 0, which means you are left with 100. 40 can go into 100 twice, which means 20 is then left over. If you then add another 0 to 20, the answer will be 200.40, which goes into 200 5 times. you are then left with 8.525, your answer.
