1/9=a/a+24 I don't get this plez someone HELP

Calling the School Subject "9th grade" may not get the right volunteer teacher reading your post. Please always try for the correct school subject. This looks like math to me and it is definitely NOT my area!

Sra

From your data, I don't get it either.

a/a = 1

That would mean:

1/9 = 1 + 24

Do you have any typos?

no i don't i asked my friend whos in trig. she finally was able to helped :)

To solve the equation 1/9 = a/(a + 24), you can start by cross-multiplying.

Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction.

In this case, you would multiply 1 (numerator of 1/9) by (a + 24) (denominator of a/(a + 24)), and multiply a (numerator of a/(a + 24)) by 9 (denominator of 1/9).

1 * (a + 24) = a * 9

Simplifying the equation, we have:

a + 24 = 9a

Next, we can solve for 'a' by isolating the variable.

Subtract 'a' from both sides of the equation:

24 = 9a - a

Simplifying further,

24 = 8a

Now, divide both sides of the equation by 8 to find the value of 'a':

24/8 = a

a = 3

Therefore, the solution to the equation 1/9 = a/(a + 24) is a = 3.
