Explain how to find a common denominator of 3/4 and 1/5 what is a common denominator of 3/4 and 1/5 show how you can rename 3/4
Paul [167]

Answer:

Common denominator = 20

New fractions are: \dfrac{15}{20}\ and\ \dfrac{4}{20}

Step-by-step explanation:

Given:

The fractions are given as:

\dfrac{3}{4}\ and\ \dfrac{1}{5}

The denominators of the first fraction is 4 and that of the second fraction is 5.

In order to find the common denominator for 4 and 5, we have to find the least common multiple of each of the numbers.

Multiples of 4 = 4, 8, 12, 16, <u>20</u>, 24, 28,....

Multiples of 5 = 5, 10, 15, <u>20</u>, 25, 30,....

Therefore, the least common multiple of 4 and 5 is 20. So, the common denominator is 20.

Now, multiply the numerator and denominator of each fraction by the same suitable number such that the denominator becomes 20.

So, for the first fraction, 4 is in the denominator.

So, 4 when multiplied by 5 gives 20.

So, we multiply the numerator and denominator of first fraction by 5. This gives,

\dfrac{3}{4}=\dfrac{3\times 5}{4\times 5}=\dfrac{15}{20}

Now, for the second fraction, 5 is in the denominator.

So, 5 when multiplied by 4 gives 20.

So, we multiply the numerator and denominator of first fraction by 4. This gives,

\dfrac{1}{5}=\dfrac{1\times 4}{5\times 4}=\dfrac{4}{20}

Therefore, the new fractions after making the denominators same are:

\dfrac{15}{20}\ and\ \dfrac{4}{20}

Find the value of x^2 + 1 divided by x^2 if x-1 divided by x =5
MrRa [10]

Answer:

x^2+1/x^2

(x+1/x)^2 = x^2+1/x^2 +2

(5)^2 = x^2+1/x^2 + 2

25 = x^2+1/x^2 + 2

25-2 = x^2+1/x^2

23 = x^2+1/x^2
