You would know by how the problem is written for example if a equation is written like this (2+3)5 you add 2+3 first then multiply by 5 to get 25 therefore you add first

Which pair is equivalent?<br> 2/6 and 2/4, or 3/6 and 1/2?<br> Explain.

lubasha [3.4K]

Answer:

3/6 and 1/2

Step-by-step explanation:

You can find which pair of fractions are equivalent by simply simplifying:

$\frac{3}{6}$

To simplify we divide the numerator and the denominator by a common integer.

$\frac{3}{6}$
$\frac{3}{6} \div3=\frac{1}{2}$
$\frac{1}{2} =\frac{1}{2}$

Second option is your answer.

Hope this helps.

Simplify: log base 3 (1/3) ...?

yarga [219]

The answer is 1.

$log_3( \frac{1}{3} )$
_____
Since $log_y(x) = \frac{log_{10}(x)}{log_{10}(y)}$ , then: $log_3( \frac{1}{3} )= \frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)}$
_____
Since $\frac{1}{x} = x^{-1}$ , then: $\frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)} = \frac{log_{10}(3^{-1} )}{log_{10}(3)}$
_____
Since $log x^{a} =a*logx$ , then: $\frac{log_{10}(3^{-1} )}{log_{10}(3)}= \frac{-1*log_{10}(3)}{log_{10}(3)}$

From here: $\frac{-1*log_{10}(3)}{log_{10}(3)}=-1*\frac{log_{10}(3)}{log_{10}(3)}=-1*1 = -1$
