Write 85% as it's fraction, as simply as possible​
cricket20 [7]

Hey ! there

Answer:

  • Simplest fraction form of 85% is <u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>.</u>

Step-by-step explanation:

Question says that we have to write the <u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>as </u><u>it's </u><u>fraction</u><u> </u><u>.</u>

<u>Solution </u><u>:</u><u> </u><u>-</u>

\quad \longrightarrow  \qquad \:85\%

We know that ,

  • Percent ( % ) = <u>1</u><u>/</u><u>100</u>

So ,

\quad \longrightarrow  \qquad \: 85 \times \dfrac{1}{100} \:

or ,

\quad \longrightarrow  \qquad \: \dfrac{85}{100}

Reducing the fraction by cancelling it by 5 :

\quad \longrightarrow  \qquad \: \dfrac{ \cancel{85}}{ \cancel{100}}

We get :

\quad \longrightarrow  \qquad \:      \pink{\underline{\boxed{\frak{\dfrac{17}{20} }}}} \quad \bigstar

Now , we can't reduce 17/20 .

  • <u>Henceforth</u><u> </u><u>,</u><u> </u><u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>is </u><u>the </u><u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>.</u>

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank
hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

24 \times 12 \frac{1}{2}  \times 12 \frac{3}{4}

Change the numbers to improper fractions

24 \times  \frac{25}{2}  \times \frac{51}{4}

We cancel out to get

3 \times 25 \times 51

3825
