The answer is 52.5 because you are suppose to multiply each number in pairs. First multiply 21/61 times 5/8.Then you will get 105/488. Multiply 105/488 times 244/1 which equals 25,620/488. Simplify to the lowest form which equals 6,405/122. Divide 6,405 divided by 122. The answer will be 52.5. That is how you will get the answer.
When reading the place value of numbers, we start from right to left.
The place values from right to left are arranged as follows:
units, tens, hundreds, thousands, ten thousands and hundred thousands.
Applying this to the given number (<span>654 321) we will find that:
1 represents the units
2 represents the tens
3 represents the hundreds
4 represents the thousands
5 represents the ten thousands
6 represents the hundred thousands</span>
