How do I do this 2/3+1/6q=q+1/3

q= 2/5 in decimal for 0.400

Step-by-step explanation:

Rewrite the whole as a fraction using  3  as the denominator :

         q     q • 3

    q =  —  =  —————

         1       3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 2-5q

 ———— • 6 = 0 • 6

  6  

Now, on the left hand side, the  6  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2-5q  = 0

Solve  :    -5q+2 = 0  

Subtract  2  from both sides of the equation :  

                     -5q = -2

Multiply both sides of the equation by (-1) :  5q = 2

Divide both sides of the equation by 5:

                    q = 2/5 = 0.400

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
