Choose the mixed numeral that is equivalent to this decimal 3.242424...

Anastaziya [24]

Answer:

First, we can write:

x

=

3

.

¯¯¯¯

24

Next, we can multiply each side by

100

giving:

100

x

=

324

.

¯¯¯¯

24

Then we can subtract each side of the first equation from each side of the second equation giving:

100

x

−

x

=

324

.

¯¯¯¯

24

−

3

.

¯¯¯¯

24

We can now solve for

x

as follows:

100

x

−

1

x

=

(

324

+

0

.

¯¯¯¯

24

)

−

(

.

¯¯¯¯

24

)

(

100

−

1

)

x

=

324

+

0

.

¯¯¯¯

24

−

x

=

x

=

Now, we can convert this improper fraction to a mixed number:

x

=

107

33

=

99

+

8

33

=

99

33

+

Please look at the attachment for the figure of circle with radius, diameter,circumference labelled.

AB is the diameter

OB and OA are radii

Radius is half of the diameter or in other words diameter is double of radius.

And circumference is the outer line of the circle

$circumference=2\pi r$
