How many 3/4s are in 3 2/4

Mathematics
1 answer:
MArishka [77]3 years ago
7 0

Answer:

the answer is 3

Step-by-step explanation:

First change the whole number (3) to quaters or fraction

3x \frac{4}{4} = \frac{12}{4}

Now, add

\frac{2}{4} + \frac{12}{4} = \frac{14}{4}   Since, we have the same common denominator

now divide

14÷4 =3.5 = 3\frac{2}{4}

Therefore, there are 3 of 3/4 with a remainder of  \frac{2}{4} in 3 \frac{2}{4}.

Solve 2x2 − 4x − 5 = 0 by completing the square.
arsen [322]
For this case we have the following polynomial:
 2x ^ 2 - 4x - 5 = 0

 Rewriting we have:
 2x ^ 2 - 4x = 5

x ^ 2 - 2x = 5/2
 Then, completing squares we have:
 x ^ 2 - 2x + (-2/2) ^ 2 = 5/2 + (-2/2) ^ 2

 Rewriting:
 x ^ 2 - 2x + (-1) ^ 2 = 5/2 + (-1) ^ 2

x ^ 2 - 2x + 1 = 5/2 + 1

(x-1) ^ 2 = 7/2
 x-1 = +/- \sqrt{7/2} x = 1 +/- \sqrt{7/2}
 Then, the solutions are:
 x1 = 1 + \sqrt{7/2} x2 = 1 - \sqrt{7/2}
 Answer:
 
x1 = 1 +  \sqrt{7/2}  

x2 = 1 - \sqrt{7/2}

and then you do 94.25%×220,000=207,350

So you can now do 207,250+220,000 (which) =427,350
