JKL is similar to PQR

so they want PR

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

$\sf { (PR)/(JL) = (QR)/(KL) }$

Plug in the numbers:

$\sf { (PR)/(6) = (15)/(9) }$

Cross multiply:

$\sf{ PR * 9 = 6 * 15}$

Isolate PR

$\sf{ PR = (6 * 15)/(9)}$

Simplify it

$\sf{ PR = 10}$

So your final answer is

$\boxed{\bf{10 centimeters}}$

I can only see the similar triangle problem, with sides 6cm, 9cm, and 15cm. Since the triangles are similar, the ratio for side lengths is the same. 6:9 simplifies to 2:3. If we try to solve ?:15 we get 10 as 10:15 is equivalent to 2:3, so the length is 10 cm

How can you write 0.15 in a fraction

Answers

In order to write a decimal as a fraction, you simply need to put all the numbers in the decimal as the numerator of the fraction, and then put a multiple of 10 with as many zeros as there are numbers to the right of the decimal point as the denominator.

0.15 = $(15)/(100)$

We can reduce our resulting fraction, since both numerator and denominator are divisible by 5.

$(15 / 5)/(100 / 5) = (3)/(20)$

Which is our final answer.
0.15 written as a fraction is $(3)/(20)$ .
