A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction
Alex73 [517]

Answer:

<h3>A) </h3>

First were going to put our numbers in perspective.

\frac{7}{4} ÷ \frac{8}{5}

But to find the improper fraction, we have to <em>cross multiply</em> these numbers.

\frac{7}{4} × \frac{8}{5}

<em>7 x 5 = 35.  </em>

<em>4 x 8 = 32.</em>

Now we have our<em> improper fraction </em>is  \frac{35}{32}

<h3>B)  </h3>

To turn our improper fraction into a <em>mixed number</em>, we will use <em>division</em>.

We know that the 32 can only go into 35 <u><em>one</em></u> time.  We also know that the bottom number <em><u>always</u></em> stays the same.  So our equation will look somewhat like this.

1\frac{?}{32}

Now to fine the top number we will have to<em> subtract 35 from 32</em> because we already know that 32 can go into 35 <u><em>one</em></u> time, so <em>35 - 32 = 3</em>.  So are mixed number will look like this.

1\frac{3}{32}

This is our <em>answer!</em>

Step-by-step explanation:

⅘ + ⅕ = 1

3 ¾ + 2 ¼ = 6

25/10 + 4/10 = 2.9

10/8 - 4/8 = 0.75

$5 ¾ - $2 ¼ = 3.5

Express 8 1/5% as a mixed number or a fraction
Alexxandr [17]

Answer:

41/5

Step-by-step explanation:

First we change the 8 and 1/5% to 8.2%

Write the fraction down as a number over one = 8.2/1

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

8.2/1 = (8.2 × 10)

(1 × 10) = 82/10

Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.
