Answer:

First were going to put our numbers in perspective.

[tex]\frac{7}{4}[/tex] ÷ [tex]\frac{8}{5}[/tex]

But to find the improper fraction, we have to cross multiply these numbers.

[tex]\frac{7}{4}[/tex] × [tex]\frac{8}{5}[/tex]

7 x 5 = 35.  

4 x 8 = 32.

Now we have our improper fraction is  [tex]\frac{35}{32}[/tex]

To turn our improper fraction into a mixed number, we will use division.

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

[tex]1\frac{?}{32}[/tex]

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

[tex]1\frac{3}{32}[/tex]

This is our answer!

Answer:

7/4 ÷ 8/5

A. First, we need to do the reciprocal of 8/5.

7/4 x 5/8 = 35/32

B. Now, we need to convert it into a mixed number. Divide 35 by 32. 32 goes into 35 one time. 35 - 32 = 3, so remainder 3. We use 1 as the whole number since 32 goes into 35 one time. We use the remainder 3 as the numerator, and 32 as the denominator.

1 3/32

Hope this helps u have a great day :)

Answer:

1/ 27

Step-by-step explanation:

[tex] = 81^{ \frac{-3}{4} } [/tex]

[tex] = (\frac{1}{81}) ^{ \frac{3}{4} } [/tex]

[tex] = (\frac{1}{3}) ^3 [/tex]

[tex] = \frac{1}{27} [/tex]

Answer:

[tex]43/100[/tex]

Step-by-step explanation:

First, make both of the denominators into 100.

Then, 3/10 would be 30/100.

Finally, you can add them to get 43/100.

Answer:

Domain=x:x is a natural number less than 6: x≠4

Range= x:x is a natural number, 3>=x<=1

Answer: I don't see what your talking about here, so I can't help you.

Step-by-step explanation:

Answer:

x = 35

Step-by-step explanation:

We can tell that these two angles are supplementary—that means that they add up to 180˚.

So, subtracting 75 from 180, we get 105. That's the value of angle 3x. Now, just divide 105 by 3. That's 35.

By that logic, x = 35.

Answer:

84/21

Step-by-step explanation:

to divide a fraction by another fraction, you must take the reciprocal of the second fraction (3/14 to 14/3) and then multiply the two fractions.

Answer:

$60.88

Step-by-step explanation:

2 yards wide and 2 yards high so thats 2 yards per side x 4 is 8, 8 x $7.61 is $60.88

Answer:

Ans(1) 167 (rounded off)

ans(2) 32 (rounded off)

Step-by-step explanation:

1. Pgs read in 12 mins= 40

  Pgs read in 1 min= 40/12 =10/3

  Pgs read in 50 mins= 10/3 ×50= 166.6

So, when rounded off, Susan can read 167 pgs in 50 mins./ (ans)

2. 2 inches distance= 7 miles

   1 inch distance= 7/2 miles

    9 inches distance= 7/2 × 9= 31.5

so, when rounded off, the cities are 36 miles apart in real life/ (ans)

100-87.06=12.94

$13(nearest dollar)

$12.94(actual)

Answer:

10

Step-by-step explanation:

because rounding 87 its 90, so 100-10=90.
