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 |
Hint |
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 the numerator and denominator by 154 |
\$ (7 \times 154)/(9 \times 154) = (1078)/(1386) \$ |
6 |
Step |
For \$(13)/(11) \$ multiply both the numerator and denominator by 126 |
\$ (13 \times 126)/(11 \times 126) = (1638)/(1386) \$ |
7 |
Step |
For \$ 8/(14) \$ multiply both the numerator and denominator by 99 |
\$ (4 \times 99)/(7 \times 99) = (396)/(1386) \$ |
8 |
Clue |
The fractions have the same denominator, so you can simply compare the numerators. The fraction with the larger numerator is the larger fraction. |
|
9 |
Hint |
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 |
\$ (13)/(11)\$ |
14 |
Solution |
Therefore, the largest fraction number is \$ (13)/(11)\$. |
