Equation: \frac{13}{15} - \frac{1}{5}

When adding or subtracting, you have to make sure they have a common denominator

So you have to multiply \frac{1}{5} by \frac{3}{3}

\frac{1}{5} * \frac{3}{3} = \frac{3}{15}

Since they both have the same denominator, you subtract

\frac{13}{15} - \frac{3}{15} = \frac{10}{15}

One thing to note is when subtracting, you DO NOT subtract the denominator, only the numerators

To reduce to the lowest terms, you need to find a common factor.
5 goes into 10 two times and goes into 15 three times

10 ÷ 5=2

15 ÷ 5=3

That leaves it with the fraction \frac{2}{3}

Answer: \frac{2}{3}

Pytahgorean theorm. A^2 + B ^2 = C^2

If f(3) = 15 and f(5) = 45, which of the following could be f(x)?
Katen [24]
F(x) = 2x² - x
f(3) = 2(3)² - 3
f(3) = 2(9) - 3
f(3) = 18 - 3
f(3) = 15

f(x) = 2x² - x
f(5) = 2(5)² - 5
f(5) = 2(25) - 5
f(5) = 50 - 5
f(5) = 45

The answer is C.
