Question

Arrange in descending order.

$785,566,344;79,887,700;978,790,980;788,556,634$

Answer 1

Compare the digit according to their place value,

So, $978,790,980>788,556,634>785,566,344>79,887,700$

Hence, the arrangement in descending order is $978,790,980;788,556,634;785,566,344;79,887,700$.
