Problem |
Identify the small fraction number given below: |
|
2 |
Step |
Given fraction numbers are |
\$(33)/(27), (25)/(14), (44)/(29)\$ |
3 |
Hint |
First, we can convert fractions to have a common denominator. |
|
4 |
Step |
The least common multiple of 27,14 and 29 is: |
13506 |
5 |
Step |
For \$ (33)/(27)\$ multiply both the numerator and denominator by 502. |
\$ (33 \times 502) / (27 \times 502) = (16566) / (13506) \$ |
6 |
Step |
For \$(25)/(14) \$ multiply both the numerator and denominator by 963. |
\$ (25 \times 963) / (14 \times 963) = (24075) / (13506) \$ |
7 |
Step |
For \$ (44)/(29) \$ multiply both the numerator and denominator by 466. |
\$ (44 \times 466) / (29 \times 466) = (20504) / (13506) \$ |
8 |
Hint |
The fractions have the same denominator, so you can simply compare the numerators. The fraction with the larger numerator is the smaller fraction. |
|
9 |
Clue |
Among the fractions \$(16566)/(13506), (24075)/(13506)\$, and \$(20504)/(13506)\$, \$(16566)/(13506)\$ has the smallest numerator, making it the smallest fraction. |
|
10 |
Step |
You can also convert them to decimals \$(16566)/(13506) \$ is approximately: |
1.22656597 |
11 |
Step |
And also \$ (24075)/(13506) \$ is approximately: |
1.84397977 |
12 |
Step |
And also \$ (20504)/(13506) \$ is approximately: |
1.51814008 |
13 |
Step |
So, the smallest fraction among \$(33)/(27), (25)/(14)\$, and \$(44)/(29)\$ is: |
\$(16566)/(13506)\$ |
14 |
Solution |
Therefore, the smallest fraction number is \$ (33)/(27) \$. |
