Answer 1

Hint: Find out the place value of each digit of the given number. Then write it in words. Like in hundreds places we have 7 and in ones and tens places we have zero. That means it is seven hundred.

Complete step-by-step answer:
To write the number 900800700 in words we need to understand the place value of each digit.
Place value describes the position or place of a digit in a number. Each digit has a place in a number.

To find out the place values of every digit in a number we always start from the right side and then we move to the left side one by one.
First we have one’s place. Here in one’s place we have 0. Therefore, we have 0 one.
Then we have tenth place. Here we have 0 in tens place. Therefore, we have 0 ten.
Then we have hundreds’ place. Here we have 7 in hundreds’ place. Therefore, we have 7 hundred.

Then we have thousands’ place. Here we have 0 in thousands’ place. Therefore, we have 0 thousand.
Then we have ten thousands’ place. Here we have 0 in ten thousands’ place. Therefore, we have zero ten thousand.
Then we have one lakhs place. Here we have 8 in one lakhs place. Therefore, we have 8 lakh.
Then we have ten lakhs’ place. Here we have 0 in ten lakhs’ place. Therefore, we have 0 ten lakh.
Then we have one crores place. Here we have 0 in one crores place. Therefore, we have 0 crore.
Then we have ten crores’ place. Here we have 9 in ten crores’ place. Therefore, we have 9 ten crores = 90 crore.
Therefore,
90 crore + 0 crore + 0 ten lakh + 8 lakh + 0 ten thousand + 0 thousand + 7 hundred + 0 ten + 0 one = ninety crore eight lakh and seven hundred.
Hence, option (a) is correct.

Note: Alternatively we can find out the correct answer by cancelling out the wrong options. Like we have 7 in hundreds places in the given number therefore we can cancel out option (d). Then we have 8 in one lakhs place and zero in ten lakhs places. Therefore, we can cancel out option (c). Like this we can cancel out option (b).
Find out the place values correctly otherwise we will get the wrong answer.
