Explain how you can tell, without computing, whether the quotient one -half divided into 6 is greater than one or less than one
Helga [31]
If you take 1/2 of a pizza and divide it up between 6 people, will you have more than 1 whole Pizza or less than 1 whole pizza?

If you divide up a fraction into smaller pieces it will always be less than 1 because it started out less than 1 and you're making it even smaller.

Answer:

\sf \dfrac{3}{4y}

Step-by-step explanation:

Simplify:

  45 = 5 * 3 * 3

  60 = 5 * 3 * 2 * 2

GCF = 5*3 = 15

           \sf \dfrac{45x^2}{60x^2y}=\dfrac{45}{60y}

                     \sf =\dfrac{45 \div 15}{60y \div 15}\\\\= \dfrac{3}{4y}

Solve: x^+4/x-1 = 5/x-1
AlexFokin [52]
The first step for solving this equation is to determine the defined range.
\frac{ x^{4}  }{x-1} = \frac{5}{x-1}, x ≠ 1
Remember that when the denominators of both fractions are the same,, you need to set the numerators equal. This will look like the following:
x^{4} = 5
Take the root of both sides of the equation and remember to use both positive and negative roots.
x +/- \sqrt[4]{5}
Separate the solutions.
x = \sqrt[4]{5}           , x ≠ 1
x = -\sqrt[4]{5} 
Check if the solution is in the defined range.
x = \sqrt[4]{5} 
x = -\sqrt[4]{5} 
This means that the final solution to your question are the following:
x = \sqrt[4]{5}          
x = -\sqrt[4]{5}
