Today in Banker’s Bounty, you will get Decimal and Fraction concept and previous year questions.
Step 1: Watch the video prepared by MockBank’s expert.
Step 2: Read the concepts that follow.
Step 3: Put a timer before you solve the previous year questions on decimal and fraction in quiz and record how much time it takes you to solve it.
Step 4: Send us questions in comments section below which took maximum time and we will tell you a faster way to solve it.
A fraction is an expression that indicates the quotient of two quantities.
Examples of fractions: 1/2, 1/3, -8/5
A fraction has two parts, namely Numerator and Denominator.
Numerator is the number at the top of the fraction and denominator is the number at the bottom of the fraction.
For example, in the fraction 1/5, 1 is the numerator and 5 is denominator.
The denominator of a fraction cannot be zero
TYPES OF FRACTION:
- Common Fraction:
A common fraction (also known as Vulgar fraction and simple fraction) is a fraction in which both numerator and denominator are integers (As with other fractions, the denominator cannot be zero). Example 1/2, 1/5, 2/7 etc.
- Decimal Fraction:
A decimal fraction is a fraction in which denominator is an integer power of ten. (The term decimals are commonly used to refer decimal fractions).
Generally, a decimal fraction is expressed using decimal notation and its denominator is not mentioned explicitly. Example1/10 = 0.11/100 = 0.011/1000 = 0.001
151/100 = 1.51Decimal fractions can also be expressed using scientific notation with negative exponents
Example: 5.192 × 10−6 is a decimal fraction which represents .000005192.
Conversion of decimal to fractionPut 1 in the denominator under the decimal point and annex with it as many zeros as is the number of digits after the decimal point. Now, remove the decimal point and reduce the fraction to its lowest terms.
0.5 = 5/10 = 1/2
0.75 = 75/100 = 3/4
1.25 = 125/100 = 5/4
