Answer:

\sf\boxed{a=6}}}

Step-by-step explanation:

Isolate the term of a from one side of the equation.

14/21=a/9

Use cross products.

\sf{14*9=21*a}

Solve by a.

A=\dfrac{14*9}{21}=\dfrac{126}{21}=\boxed{\sf{6}}

<u>a=6</u>

So, the final answer is a=6.

I hope this helps! Let me know if my answer is wrong or not.

Tyler used 1 1/2 gallons of paint to paint 5/7 of a fence. How many gallons will it take to paint the whole fence?
Mademuasel [1]

9514 1404 393

9514 1404 393

Answer:

  1) (1 1/2)(7/5) = g

  2) (1 1/2)/(5/7) = g

Step-by-step explanation:

1) Tyler has painted 5/7 of the 7/7 of the fence. So the total amount of the fence is (7/7)/(5/7) = 7/5 as much as what was already painted.

The total amount of paint needed is then 7/5 the amount already used:

  g = (7/5)(1 1/2) . . . . . gallons of paint needed for the whole fence

__

2) If g gallons are required for the whole fence, the amount used so far for 5/7 of the fence is 5/7 of the quantity required:

  (5/7)g = 1 1/2

  g = (1 1/2)/(5/7) . . . . division expression for the paint needed
