0.580 repeating as a fraction
ElenaW [278]

Answer:

Write out your decimal as the numerator of a fraction:

0.50 /1

Multiply to remove the 2 decimal places:

0.50 /1 ×  100 /100=  50 /100

Find the Greatest Common Factor of 50 and 100:

GCF is 50

Divide both numerator and denominator by 50:

50 ÷ 50

100 ÷ 50 =  1 /2

therefore your answer is 1/2

Hope this helps! (づ ̄3 ̄)づ╭❤~

What are the solutions of 3(2m − 1) ≤ 6m − 2?
kaheart [24]

Hello from MrBillDoesMath!

Answer:

The solution set is the set all all real number m

 

Discussion:

3(2m-1) <= 6m-2       =>

3*2m - 3*1 <= 6m-2  =>

6m - 3 <.= 6m-2       =>   (Subtract 6m from both sides)

0-3 <= -2     =>

-3 < = -2      


As -3 <=-2 is always true the solution set is the set all all real number m

Regards,  

MrB
