What is a fraction of a fraction
Vikentia [17]
<h3> - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - </h3>

➷ When it comes to dividing fractions, there is a rule you must now.

It's called Keep Flip Change.

I'll give you an example:

\frac{2}{7} / \frac{4}{6}

Keep the first fraction exactly as it is

Flip the second fraction upside down (switch the numerator and denominator around)

Change the sign to a multiplication.

This is how it should look:

\frac{2}{7} *\frac{6}{4}

Now you just multiply them as you normally would to get an answer of:

\frac{12}{28}

➶Hope This Helps You!

➶Good Luck :)

➶Have A Great Day ^-^

Which of the following is a factor of (x+y)³-(x+y)³
IgorC [24]

▬▬▬▬▬▬▬▬▬▬▬▬▬▬

<h3>Answer :</h3>

The factor of (x + y)³- (x³ + y³) is <u>3xy</u>

<h3>Step By Step Solution :</h3>

→ (x + y)³- (x³ + y³)

→ (x + y) - (x + y)(x² - xy + y²) [Using identity a³ + b³ = (a + b)(a²- ab+ b²)]

→ (x + y)(x² + y² + 2xy - x² + xy - y²)[Using identity, (a + b)² = (a² + b²+ 2ab)]

→ (x + y) (3xy)

→ 3xy

∴ Option d. 3xy is correct!
