Answer:

Your answer is 81.

Step-by-step explanation:

The median means the middle number, so you put the numbers in order from least to greatest, and the middle number is your median. However, if you have an even set of numbers, you chose the direct number in the middle of those 2 numbers for an example, if 6&7 were both your medians, it'd be 6.5

What’s the answer to m/3-2m/5=1/5

natta225 [31]

Answer:

m = - 3

Step-by-step explanation:

$\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}$

It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.

$15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}$
