Question

What is successive magnification?

• A. The process of visualization of presentation of numbers on the number line through a magnifying glass
• B. Locating the irrational numbers on the number line
• C. The process of visualization of numbers greater than 90 on the number line
• D. None of the above

Answer 1

The correct option is A The process of visualization of presentation of numbers on the number line through a magnifying glass

Suppose, we need to locate the decimal 4.36 on the number line. Now, we know that the number is between 4 and 5 on the number line. Now, lets divide the portion between 4 and 5 into 10 equal parts.

Then, it will represent 4.1, 4.2 ......... 4.9 . Now we know that 4.36 lies between 4.3 and 4.4. Now, lets divide the portion between 4.3 and 4.4 into 10 equal parts. Then, these will represent 4.31, 4.32, 4.33, 4.34, 4.35, 4.36 .......... 4.39.
So, we have located the desired positive number on the number line. This process is called the process of successive magnification.
