Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Identify the large fraction number given below \$6/5,15/5,12/5,7/3\$
2	Step	The given fraction numbers are	\$6/5,15/5,12/5,9/3\$
3	Step	First, we can convert fractions to have a common denominator.
4	Step	The least common multiple of 5 and 3 is	15
5	Step	For \$ 6/5\$ multiply both the numerator and denominator by 3	\$ (6 * 3) / (5 * 3) = 18/15 \$
6	Step	For \$ 15/5 \$ multiply both the numerator and denominator by 3	\$ (15 * 3) / (5 * 3) = 45/15 \$
7	Step	For \$ 12/5 \$ multiply both the numerator and denominator by 3	\$(12 * 3) / (5 * 3) = 36 / 15 \$
8	Step	For \$ 7/3 \$ multiply both the numerator and denominator by 5	\$(7 * 5) / (3 * 5 ) = 35 / 15 \$
9	Step	The fractions have the same denominator, so you can simply compare the numerators. The fraction with the larger numerator is the larger fraction.
10	Step	Among the fractions \$18/15\$, \$45/15 \$, \$36/15\$, and \$ 35/15 \$, \$45/15\$ has the largest numerator, making it the largest fraction.
11	Step	You can also convert them to decimals \$18/15\$ is approximately	1.2
12	Step	And also \$45/15\$ is approximately	3
13	Step	And also \$36/15\$ is approximately	2.4
14	Step	And also \$35/15\$ is approximately	2.3
15	Step	So, the largest fraction among \$6/5, 15/5, 12/5 \$, and \$7/3\$ is	\$ 45/15 \$
16	Step	Therefore, the largest fraction number is	\$ 15/5 \$
17	Sumup	Can you summarize what you’ve understood in the above steps?
18	Choice.A	This is incorrect because it is the smaller fraction	\$9/3\$
19	Choice.B	This is incorrect because it is the smaller fraction	\$6/5\$

Problem

Identify the large fraction number given below
\$6/5,15/5,12/5,7/3\$

Step

The given fraction numbers are

\$6/5,15/5,12/5,9/3\$

Step

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

Step

The least common multiple of 5 and 3 is

Step

For \$ 6/5\$ multiply both the numerator and denominator by 3

\$ (6 * 3) / (5 * 3) = 18/15 \$

Step

For \$ 15/5 \$ multiply both the numerator and denominator by 3

\$ (15 * 3) / (5 * 3) = 45/15 \$

Step

For \$ 12/5 \$ multiply both the numerator and denominator by 3

\$(12 * 3) / (5 * 3) = 36 / 15 \$

Step

For \$ 7/3 \$ multiply both the numerator and denominator by 5

\$(7 * 5) / (3 * 5 ) = 35 / 15 \$

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 \$18/15\$, \$45/15 \$, \$36/15\$, and \$ 35/15 \$, \$45/15\$ has the largest numerator, making it the largest fraction.

Step

You can also convert them to decimals \$18/15\$ is approximately

1.2

Step

And also \$45/15\$ is approximately

Step

And also \$36/15\$ is approximately

2.4

Step

And also \$35/15\$ is approximately

2.3

Step

So, the largest fraction among \$6/5, 15/5, 12/5 \$, and \$7/3\$ is

\$ 45/15 \$

Step

Therefore, the largest fraction number is

\$ 15/5 \$

Sumup

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

Choice.A

This is incorrect because it is the smaller fraction

\$9/3\$

Choice.B

This is incorrect because it is the smaller fraction

\$6/5\$

Choice.C

This is incorrect because it is the smaller fraction

\$12/5\$

Choice.D

This is correct because it is the larger fraction

\$15/5\$
