I want to know the simple way to add fractions like I have a problem with getting the answer to 1/6+1/8=

Jobisdone [24]

You find the lowest common denominator of both fractions, which in this case is 24.
1/6 is equivalent to 4/24 and 1/8 is equivalent to 3/24.
4/24 + 3/24 = 7/24

Plums are $3.25 for 2 pounds, i need 4 pounds. how much will it cost

olasank [31]

<u /> $\frac{3.25}{2lbs} = \frac{x}{4lbs} \\ \frac{3.25}{2} * \frac{2}{2} = \frac{x}{4} \\ \frac{3.25 * 2}{2*2} = \frac{x}{4} \\ 3.25*2 = x \\ x = 6.50$
It will cost $6.50 for four pounds of plums.

Hope this helps!

Please help to solve this<br>Find H.C.F <br>m^3 - 1, m^4 + m^2 + 1, m^2+ m + 1

Nikitich [7]

Answer:

m^2+m+1

Step-by-step explanation:

m^3 - 1= (m-1)(m^2+m+1)
m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
m^2+ m + 1

HCF= m^2+m+1 which is the factor of all three polynomials
