How to Solve Quickly Decimals and Fractions

Definition:
- Decimals and fractions are two notations to represent a number.
- A decimal number is a number whose place value is based on 10s.
- Also, whole numbers are actually decimal numbers which are greater than or equal to zero.
- The following section describes the three examples of how decimals and fractions are calculated.

Type 1: Find the greatest or smallest fraction

Question 1. Which among $\frac{5}{7}$ and $\frac{9}{2}$ is greater?

Options:

A. $\frac{5}{7}$

B. $\frac{9}{2}$

C. Both are equal

D. Cannot be Determined

Solution: $\frac{5}{7}$ = 0.71

$\frac{9}{2}$ = 4.5

The decimal values of the above fractions clearly indicate that the value of $\frac{9}{2}$ is more than $\frac{5}{7}$ . Therefore, $\frac{9}{2}$ is the greater number among the two.

Correct Answer: B

Question 2. Which among the given numbers is greater $\frac{5}{8}$ or $\frac{1}{2}$ ?

Options:

A. $\frac{5}{8}$

B. $\frac{1}{2}$

C. Both are equal

D. Cannot be Determined

Solution: $\frac{5}{8}$ = 0.62

$\frac{1}{2}$ = 0.5

The decimal value of $\frac{5}{8}$ is greater than that of $\frac{1}{2}$ . Therefore, it is greater than $\frac{1}{2}$ .

Correct Answer: A

Question 3.Which among $\frac{4}{7}$ and $\frac{9}{7}$ is greater?

Options:

A. $\frac{4}{7}$

B. $\frac{9}{7}$

C. Both are equal

D. Cannot be Determined

Solution: $\frac{4}{7}$ = 0.57

$\frac{9}{7}$ = 1.28

Since the decimal value of $\frac{9}{7}$ is greater, it is the greater number between the given two numbers.

Correct Answer: B
