75 miles to 225 miles as a fraction in simplest form

Pie

Answer:

$\frac{1}{3}$

Step-by-step explanation:

When reducing a number to its lowest term you use the GCF of the denominator and numerator then divide using this number. :

$\frac{75}{225}$ ÷ $\frac{75}{75}$ = $\frac{1}{3}$

The gcf of 75 and 225 is 75 so we divide both the numerator and denominator by 75.

Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75

AnnyKZ [126]

$\huge\text{Hey there!}$

$\huge\textbf{What does \boxed{median} mean in math?}}$

$\boxed{\text{Median}}\rightarrow\textsf{ is the number in the middle.}$

$\huge\textbf{How do you find the \boxed{median}?}$

$\text{You can found it by putting the numbers from \bf least to greatest.}$

$\huge\textbf{Question reads....}$

$\text{Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95,}\\\text{72, 75}$

$\huge\textbf{Equation:}$

$\text{91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75}$

$\huge\textbf{Rearrange the problems to:}$

$\text{69,71,71,71,72,74,75,82,87, 89,89,91,95,95}$

$\huge\textbf{The expression:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\huge\textbf{Simplify it:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\mathsf{\dfrac{157}{2} = median}$

$\mathsf{257\div2 = median}$

$\mathsf{78.5 = median}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{78.5}}\huge\checkmark$
