Answer:

√30-√18+√55-√33/2

Step-by-step explanation:

What is the following quotient? sqrt6+sqrt11/sqrt5+sqrt3​

Given the expression

√6+√11/√5+√3

Rationalize

√6+√11/√5+√3 × √5-√3/√5-√3

= √30-√18+√55-√33/√25-√9

= √30-√18+√55-√33 /5-3

= √30-√18+√55-√33/2

48 divided by four fifths
Fed [463]

Answer:

The answer is 60.

Step-by-step explanation:

\frac{48}{1}÷\frac{4}{5}

Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):

\frac{48}{1}×\frac{5}{4}

Cross-cancel(common factor of 4):

\frac{12}{1}×\frac{5}{1}

Multiply:

\frac{12 x 5}{1 x 1}

Simplify:

12 x 5=60

The answer is 60

hope this helps :)
