Question

i) Fifty-two hundredths is same as ________
ii) What is \[20 \div 10\]

Answer 1

Hint: Here in this question, we have two sub questions. The first question is related to the decimal. The hundredth will represent the place value, so considering the place value we simplify the first question. The second question is a simple division, by using the tables of multiplication or by cancelling we get the solution for the given question.

Complete step by step solution:
I.In mathematics we have different kinds of numbers namely, natural numbers, whole numbers, Integers, rational numbers, irrational numbers and real numbers.
Now consider the first question
Fifty two hundredths
The hundredth place value written as \[\dfrac{1}{{100}}\]
This is written as
\[ \Rightarrow 52 \times \dfrac{1}{{100}}\]
On simplifying we have
\[ \Rightarrow \dfrac{{52}}{{100}}\]
On dividing 52 by 100 we have
\[ \Rightarrow 0.52\]
Hence we have got the solution for the given question.

II.Now we solve the second question
Consider \[20 \div 10\]
This can be written in the form of fraction
\[ \Rightarrow \dfrac{{20}}{{10}}\]
On cancelling the zeros in the numerator and denominator we have
\[ \Rightarrow \dfrac{2}{1}\]
Since the denominator’s value is 1. We neglect the value of 1, we write the numerator value.
\[ \Rightarrow 2\]
The second question can be solved in another way.
Consider \[20 \div 10\]
This can be written in the form of fraction
\[ \Rightarrow \dfrac{{20}}{{10}}\]
By the tables of multiplication of 10, When 10 is multiplied by 2, the answer will be 20. So we have
\[ \Rightarrow 2\]
Hence we have got the solution for the given question.

Note: The students do not get confused by seeing the word hundredths. The fifty two hundredths means it is not 5200. The hundredth will represent the place value. So students know about the place value system of the decimal number. Students must know the tables of multiplication.
