If anyone can help w/ fractions reducing them to the lowest term

1 answer:

Mandarinka [93]4 years ago

To reduce fractions to lowest terms, find the biggest number that divides evenly into <u>both</u> the numerator and the denominator. Then divide and your new fraction should be in lowest terms if you used the biggest number. This number is called the Greatest Common Factor of the numerator and denominator.

Example:
5/10 reduces to 1/2 because 5 divides into 5 once and into 10 twice.

12/15 reduces to 4/5 because 3 divides into 12 four times, and into 15 five times.

What is the percent of the number 2 in the number 625

Tpy6a [65]

Write 2/625 and then multiply the result by 100%: 200%/625 can be re-written as 8% / 25 by dividing both 200 and 625 by 25.

8% / 25 can be thought of as "eight twenty-fifths of 1 percent. (ANSWER)

Using my calculator, I found that 2/625 is 0.0032. Mult. that by 100% results in 0.32. Note that 8/25 = 0.32.

Log5 (x squared - 9) = 0

andreev551 [17]

Answer:

$x=3,\:x=-3$

Step-by-step explanation:

Given the equation

$\log _{10}\left(5\right)\left(x^2-9\right)=0$

Divide both sides by $\log _{10}\left(5\right)$

$\frac{\log _{10}\left(5\right)\left(x^2-9\right)}{\log _{10}\left(5\right)}=\frac{0}{\log _{10}\left(5\right)}$

Simplify

$x^2-9=0$

Add 9 to both sides

$x^2-9+9=0+9$

Simplifying

$x^2=9$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{9},\:x=-\sqrt{9}$

as

$\sqrt{9}\:=3$

$-\sqrt{9}=-3$

Therefore,

$x=3,\:x=-3$

If you divided 48 objects into sets of 7, how many sets of 7 could you make, and how many are left over?

Klio2033 [76]

Answer:

6

Step-by-step explanation:

No. objects in one set = 7

Let there be n set

Then, No. objects in n set = 7*n = 7n

Given that total no of objects are 48

Thus,

7n = 48

n = 48/7 = (42+6)/7 = 42/7 + 6/7 = 6 + 6/7

n = 6 + 6/7

Thus, there will be 6 set which has 7 objects. fraction means one set is fraction 6/7 but set cannot be in fraction hence negating it.

Now, total objects in 6 sets = 6*7 = 42.

No. of objects left = 48 - 6 = 6
