Question

Write the following numbers in digits by using an international place value chart. Also write them in expanded form.
Fifty five million twenty nine thousand seven.

Answer 1

Hint:Chart out the place value chart and find the digits with the help of the chart. Expand the digit obtained and find the place value of each digit with reference to the place value chart.In a place value chart, the digits are grouped in the threes in a big number. The number is read from left to right as billion-million-thousands-ones.Now let us draw the place value chart of the international system.

Complete step-by-step answer:

\[\therefore \]100,000 = 100 thousand
1,000,000 = 1 million
10,000,000 = 10 million
100,000,000 = 100 million
We have been given fifty five million twenty nine thousand seven. Let us find the digits by placing it in the place value chart.

Thus fifty five million twenty nine thousand seven = 55029007.

We can explain it by,
\[55029007=5\times 10,000,000+5\times 1,000,000+0\times 100,000+2\times 10,000+9\times 1,000+0\times 100+0\times 10+7\times 1.\]
Place value of 5 is \[5\times 10,000,000=50,000,000\] and the place is ten million.
Place value of 5 is \[5\times 1,000,000=5,000,000\] and the place is one million.
Similarly 2 is \[2\times 10,000=20,000\] and the place is ten thousand.
Place value of 9 is \[9\times 1,000=9,000\] and the place is one thousand.
Place value of 7 is \[7\times 1=7\] and the place is one.

Note:The place value of digit 0 at any place is zero. Thus the zeroes in 55029007, their place value will be zero unlike the digits 5, 5, 2, 9 and 7 which have place values.
