Solve the following proportion for 17/13=9/u
ValentinkaMS [17]

Answer:

<h2>u = 6.88</h2>

Solution,

\frac{17}{13}  =  \frac{9}{u}

Sinplify the equation using cross multiplication

17 \times u = 13 \times 9

Calculate the product

17u = 117

Divide both sides of the equation by 17

\frac{17u}{17}  =  \frac{117}{17}

Calculate

u = 6.88

Hope this helps...

Good luck on your assignment..

Please help (puppy eyes)
-Dominant- [34]
First we have to find the decimal equivalent by dividing.
5 / 8 = 0.625

It can't be an Integer because decimals can't be intergers, so that's ruled out

It can't be repeating as it does end, so that's also ruled out

Since the decimal does end it can't be non-terminating, non-repeating

So the answer is Terminating Decimal by process of elimination
