Answer:
Customary:
Foot, inch, mile, yard.
Metric:
Centimeter, kilometer, meter.
Both:
Area, height, formula, perimeter.
2x4=8 2x2=4 4+8=12, so it is A
Given:
Consider the given expression is:
![\dfrac{h+f}{3}+\dfrac{f+k}{2}+\dfrac{4h-k}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7Bh%2Bf%7D%7B3%7D%2B%5Cdfrac%7Bf%2Bk%7D%7B2%7D%2B%5Cdfrac%7B4h-k%7D%7B5%7D)
To find:
The simplified form of the given expression.
Solution:
We have,
![\dfrac{h+f}{3}+\dfrac{f+k}{2}+\dfrac{4h-k}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7Bh%2Bf%7D%7B3%7D%2B%5Cdfrac%7Bf%2Bk%7D%7B2%7D%2B%5Cdfrac%7B4h-k%7D%7B5%7D)
Taking LCM, we get
![=\dfrac{10(h+f)+15(f+k)+6(4h-k)}{30}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B10%28h%2Bf%29%2B15%28f%2Bk%29%2B6%284h-k%29%7D%7B30%7D)
![=\dfrac{10h+10f+15f+15k+24h-6k}{30}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B10h%2B10f%2B15f%2B15k%2B24h-6k%7D%7B30%7D)
![=\dfrac{34h+25f+9k}{30}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B34h%2B25f%2B9k%7D%7B30%7D)
Therefore, the required simplified fraction for the given expression is
