Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Identify the large fraction number given below \$7/9 , 13/11, 8/14\$
2	Step	Given fraction numbers are	\$7/9 , 13/11, 8/14\$
3	Step	First, we can convert fractions to have a common denominator.
4	Step	The least common multiple of 9,11 and 14 is	1386
5	Step	For \$ 7/9\$ multiply both the numerator and denominator by 154	\$ (7 * 154) / (9 * 154) = 1078 / 1386 \$
6	Step	For \$13/11 \$ multiply both the numerator and denominator by 126	\$ (13 * 126) / (11 * 126) = 1638 / 1386 \$
7	Step	For \$ 8/14 \$ multiply both the numerator and denominator by 99	\$ (4 * 99) / (7 * 99) = 396 / 1386 \$
8	Step	The fractions have the same denominator, so you can simply compare the numerators. The fraction with the larger numerator is the larger fraction.
9	Step	Among the fractions \$1078 / 1386 \$, \$1638 / 1386\$, and \$ 396 / 1386 \$, \$ 1638 / 1386 \$ has the largest numerator, making it the largest fraction.
10	Step	You can also convert them to decimals \$ 1078 / 1386 \$ is approximately	0.777777
11	Step	And also \$ 1638 / 1386 \$ is approximately	1.18181818
12	Step	And also \$ 396 / 1386 \$ is approximately	0.28571428
13	Step	So, the largest fraction among \$7/9, 13/11\$, and \$8/14\$ is	\$ 1638 / 1386 \$
14	Step	Therefore, the largest fraction number is	\$ 13/11 \$
15	Sumup	Can you summarize what you’ve understood in the above steps?
16	Choice.A	This is incorrect because it is the smaller fraction	\$8/14\$
17	Choice.B	This is incorrect because it is the smaller fraction	\$7/9\$
18	Choice.C	This is correct because it is the larger fraction	\$13/11\$

Problem

Identify the large fraction number given below
\$7/9 , 13/11, 8/14\$

Step

Given fraction numbers are

\$7/9 , 13/11, 8/14\$

Step

First, we can convert fractions to have a common denominator.

Step

The least common multiple of 9,11 and 14 is

1386

Step

For \$ 7/9\$ multiply both the numerator and denominator by 154

\$ (7 * 154) / (9 * 154) = 1078 / 1386 \$

Step

For \$13/11 \$ multiply both the numerator and denominator by 126

\$ (13 * 126) / (11 * 126) = 1638 / 1386 \$

Step

For \$ 8/14 \$ multiply both the numerator and denominator by 99

\$ (4 * 99) / (7 * 99) = 396 / 1386 \$

Step

The fractions have the same denominator, so you can simply compare the numerators. The fraction with the larger numerator is the larger fraction.

Step

Among the fractions \$1078 / 1386 \$, \$1638 / 1386\$, and \$ 396 / 1386 \$, \$ 1638 / 1386 \$ has the largest numerator, making it the largest fraction.

Step

You can also convert them to decimals \$ 1078 / 1386 \$ is approximately

0.777777

Step

And also \$ 1638 / 1386 \$ is approximately

1.18181818

Step

And also \$ 396 / 1386 \$ is approximately

0.28571428

Step

So, the largest fraction among \$7/9, 13/11\$, and \$8/14\$ is

\$ 1638 / 1386 \$

Step

Therefore, the largest fraction number is

\$ 13/11 \$

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

This is incorrect because it is the smaller fraction

\$8/14\$

Choice.B

This is incorrect because it is the smaller fraction

\$7/9\$

Choice.C

This is correct because it is the larger fraction

\$13/11\$

Choice.D

This is incorrect because option C is the correct answer

All the above
