What percent of 120 is 28.8
12345 [234]

Answer:

24

Step-by-step explanation:

Step 1: We make the assumption that 120 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=120$.

Step 4: In the same vein, $x\%=28.8$.

Step 5: This gives us a pair of simple equations:

$100\%=120(1)$.

$x\%=28.8(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{120}{28.8}$

Rena spent 6 days reading her book completing the same fraction of the book each day if she had a total of 8/9 of her book after
Artyom0805 [142]

Answer:

The fraction of the book that Rena read every day is \frac{4}{27}

Step-by-step explanation:

Rena spent 6 days reading her book completing the same fraction of the book every day and you want to know the fraction of the book she read each day. Knowing that Rena had a total of 8/9 of her book read after 6 days, then you simply divide the total amount of the book read during those days by 6, the number of days:  

\frac{8}{9}÷6

To divide a fraction by a whole number, you must convert the whole number into a fraction, finding the reciprocal of that fraction, and multiply it by the first fraction. That is, you must find the reciprocal of the number that is after the division symbol; and then you multiply the first number (the one before the division symbol) by the reciprocal of the second number (the one after the division symbol). Remember that to find the reciprocal of a number, you simply have to change the numerator and denominator of the number.

Since 6 can be considered to be a fraction equal to \frac{6}{1}, by inverting the number, then you get \frac{1}{6}

Then:

\frac{8}{9}÷6= \frac{8}{9} *\frac{1}{6}

Now you multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final solution.

\frac{8}{9}÷6= \frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}

Finally, simplifying the fraction:

\frac{8}{9}÷6= \frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}=\frac{4}{27}

So:

\frac{8}{9}÷6= \frac{4}{27}

<u><em>The fraction of the book that Rena read every day is </em></u>\frac{4}{27}<u><em></em></u>

1.06(12.95+x)=31.27 solve for x
OverLord2011 [107]

Answer:

<h2>x = 16.55</h2>

Step-by-step explanation:

1.06(12.95 + x) = 31.27

<u>Multiply the terms in the bracket</u>

That's

13.727 + 1.06x = 31.27

<u>Subtract 13.727 from both sides</u>

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

<u>Divide both sides by 1.06</u>

That's

\frac{1.06x}{1.06}  =  \frac{17.543}{1.06}  \\ x =  \frac{17.543}{1.06}

We have the final answer as

<h3>x = 16.55</h3>

Hope this helps you
