Larger numbers

If we add one more to the greatest 6-digit number we get the smallestlargest 7-digit number. It is called ten lakh.

If we add one more to the largestsmallest 7-digit number we get the smallest 8-digit number. The smallest 8-digit number is called one crore.

Let’s use a 1←10 machine to see if that is actually the case. The last box has 9 dots. Lets see what happens when we add one more dot to it. Click somewhere in the 1s cell to add 1:

Continuing:

Remember

1 hundred = 10 tens

1 thousand = hundreds = tens

1 lakh = thousands = hundreds

1 crore = lakhs = thousands

1.What is 10–1= ?

2. What is 100–1=?

3. What is 10,000 – 1 =?

4. What is 1,00,000 – 1 =?

5. What is 1,00,00,000 – 1 =?

1)10,100,10000,100000,10000000 are the smallest 2-digit, 3-digit,5-digit,6-digit,8-digit numbers respectively.

2)9,99 ,9999,99999,9999999 are the greatest 1-digit,2-digit,4-digit,5-digit,-digit numbers respectively.

3)We can say that the predecessor of the smallest n-digit number is the grestest (n-1)-digit numbers.

Example: *In the above case:*Predecessor of the smallest 2-digit number(10) is greatest -digit number(9).In this case n=2;Try to apply this concept for the remaining cases.

Match the quantities to the number of digits needed to specify the quantity.

1. Give an example where the number of things counted would be more than 6-digit number.mansion costcycle costschool bag

2. Starting from the greatest 6-digit number, write the previous 3 numbers in descending order.,,

3. Starting from the smallest 8-digit number, write the next 3 numbers in ascending order and read them.,,
