Find PR<br><br> KL is 28<br> KM is 18<br> PT is 15.75
stepan [7]

Answer:

PR = 24.5

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{KL}{PR} = \frac{KM}{PT}, that is

\frac{28}{PR} = \frac{18}{15.75} ( cross- multiply )

18PR = 28 × 15.75 = 441 ( divide both sides by 18 )

PR = 24. 5

What is 25 2/3 - 15 1/3 =
Ira Lisetskai [31]

Answer:

10 1/3

Step-by-step explanation:

Convert mixed numbers into improper fractions (whole number × denominator + numerator)

25 2/3 and 15 1/3

25 × 3 + 2 = 75 + 2 = 77

Put the number over the same denominator

77/3

15 × 3 + 1 = 45 + 1 = 46

Put the number over the same denominator

46/3

77/3 - 46/3

They have common denominators so we can simply subtract the numerator values

77 - 46/3

31/3

To convert it back to a whole number, find how many times 3 fits into 31 evenly

It fits 10 times evenly with 1 remainding which looks like:

10 1/3
