Answer 1

Answer:

(E) 137137

Explanation:

• Everyday activities include the use of numbers. Numerols are a common name for them. Without numbers, we are unable to count items, dates, hours, money, etc. These numerals are sometimes used for labelling and occasionally for measuring. Numbers are able to execute mathematical operations on them due to their inherent characteristics. Both quantitative and verbal expressions of these quantities are available. As an illustration, the number 2 is written as 2, the number 25 as 25, etc. To learn further, students might practise writing the numbers from 1 to 100 in words.

• We discover that there are several kinds of numbers in mathematics. They are whole numbers and natural numbers, as well as odd and even, rational and irrational numbers, etc.
