Answer 1

Hint: We will use the digits and their positions mentioned in the number name to write the appropriate. We will use a place value chart to find the positions of the digits in the number.

Ten Crores	Crores	Ten Lakhs	Lakhs	Ten Thousands	Thousands	Hundred	Tens	Ones
10,00,00,000	1,00,00,000	10,00,000	1,00,000	10,000	1000	100	10	1

Complete step-by-step answer:
Numeral stands for numeric value of number.
We need to know digits and their places to write the correct number.
We have been given the number names of certain numerals.
We will read these number names, find out the digits used, the places of the digits and then write the number accordingly.
Also, the place value chart helps to write the digit in the correct position.

Ten Crores	Crores	Ten Lakhs	Lakhs	Ten Thousands	Thousands	Hundred	Tens	Ones
10,00,00,000	1,00,00,000	10,00,000	1,00,000	10,000	1000	100	10	1

Thus, Five lakh forty thousand six hundred fifty is written as 5,40,650
b. Fifteen lakh thirty-six thousand four hundred thirty-nine is written as 15,36,439
c. Five crore fifty-four lakh twenty-seven thousand eight hundred sixty-nine is written as 5,54,27,869
d. Six crores five lakh forty-three thousand sixty-five is written as 6,05,43,065
e. Eighty-three lakh forty-four thousand seven is written as 83,44,007
f. Seventy-eight lakh six thousand five hundred six is written as 78,06,506
g. Eight crore seven lakh eighty-six thousand sixty-eight is written as 8,07,86,086
h. Four crore seven hundred is written as 4,00,00,700

Note: If the digit of a certain place is not given, we will use 0 in that place. For example, in the number name Eighty-three lakh forty-four thousand seven, we are not given the digit of hundredth and tenth place, hence, we write it like 83,44,007.
