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>

8 ft 6 inches is greater or less than 100 inches?
Romashka [77]
It would be greater, because 1 foot is equal to 12 inches. 8 times 12 is 96. Then 96 plus 6 inches in 102. So it would be greater.

If f(x) = 3^2 + 10x and g(x) = 2x-4, find (f-g)(x).
Marat540 [252]

What we know:      

f(x)=3^2+10x\\g(x)=2x-4                

(Also, 3^2=9)

What we need to solve:

(f-g)(x)             (This is equal to f(x)-g(x))

How you have to subtract f(x) with g(x) to get:

(f-g)(x) = f(x)-g(x) = 9+10x+2x-4 = 12x+5

Thus, the answer would be:

12x+5
