Evaluate 33/5 - 1/10

azamat

Answer:

$\large\boxed{\dfrac{13}{2}=6\dfrac{1}{2}=6.5}$

Step-by-step explanation:

We have the different denominators.

The common denominator is 10.

$\dfrac{33}{5}=\dfrac{33\cdot2}{5\cdot2}=\dfrac{66}{10}$

We can subtract these fractions now.

$\dfrac{33}{5}-\dfrac{1}{10}=\dfrac{66}{10}-\dfrac{1}{10}=\dfrac{66-1}{10}=\dfrac{65:5}{10:5}=\dfrac{13}{2}\\\\\dfrac{13}{2}=\dfrac{12+1}{2}=6\dfrac{1}{2}$

What is the median of the following data values? 108,102,43,100,22

PolarNik [594]

<u>Answer:</u> 100

<u>Reasoning:</u> The median is the "middle value" and to find it put the numbers in order from least to greatest.

22, 43, 100, 102, 108.

now take a number from both sides

43, 100, 102

Once again.

100

So 100 is the median.
