change the mixed numbers to improper fractions before dividing

1 $\frac{1}{4}$ = $\frac{5}{4}$ and 15 $\frac{1}{3}$ = $\frac{46}{3}$

divide contents of box by a serving

$\frac{46}{3}$ ÷ $\frac{5}{4}$

change ÷ to × and turn the second fraction upside down

= $\frac{46}{3}$ × $\frac{4}{5}$

= $\frac{184}{15}$ = 12.26666 = 12 complete servings

What is the least common denominator of 1/9 and 2/3

Kipish [7]

Answer:

Step-by-step explanation:

All u have to do is think only about two denominators, 9 and 3

And then memorize the multiplication of any number out of these two, until u get a number which is divisible by the other number. Its like,

9×1= 9

is it divisible by 3?

9/3= 3

Oh yes, it is divisible by 3 with no remainings. So that is the least common denominator

The Quadratic Formula, x equals negative b plus or minus the square root of b squared minus 4 times a times c, all over 2 times

DedPeter [7]

Answer:

The correct option is 2 .

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is <u> 2 . </u>

$x=\dfrac{4\pm\sqrt{2}}{2}$

Step-by-step explanation:

For a Quadratic Equation ax² + bx + c = 0

By Formula Method we get

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

So we have Quadratic Equation is 2x² - 8x + 7 = 0

On Comparing we get

$a=2\\b=-8\\c=7$

Substituting a , b, c values we get

$x=\dfrac{-(-8)\pm\sqrt{(-8)^{2}-4(2)(7)}}{2(2)}\\\\x=\dfrac{8\pm\sqrt{64-56}}{4}\\\\x=\dfrac{8\pm\sqrt{8}}{4}\\\\x=\dfrac{8\pm2\sqrt{2}}{4}\\\\x=2(\dfrac{4\pm\sqrt{2}}{4})\\\\x=\dfrac{4\pm\sqrt{2}}{2}$

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is <u> 2 . </u>
