How much of the circle is shaded? 4/7+1/3 HELP

First find how much of the circle is NOT shaded.

You know the unshaded parts are 4/7 and 1/3, so combine them.

To combine fractions, they need to have the same denominator. To figure out what value/number to make the denominator, find the least common denominator(LCD) of 7 and 3:

3: 3, 6, 9, 12, 15, 18, 21, 24

7: 7, 14, 21, 28

The LCD of 7 and 3 = 21, so:

 Multiply 4/7 by 3/3, and multiply 1/3 by 7/7 to make the denominator the same

   Now combine the fractions

Now that you've found the unshaded part of the circle, the part left over will be the shaded part of the circle:

 or      (1 or 21/21 is the fraction of the entire/whole circle, so you subtract it by the unshaded part to find the fraction left over which will = the part of the circle that is shaded)

    This is how much the circle is shaded

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
