Answer:

5/7

Step-by-step explanation:

An easy way to find the biggest fraction is to divide the numerator by the dominator to turn it into a decimal, a more complexed way would be to do much more work and turn all fractions into having the same dominator

5/7 = 0.714

2/12 = 0.166

15/40 = 0.375

8/20 = 0.4

Answer:

5/7 is the largest

Step-by-step explanation:

$\frac{5}{7}$ is the largest fraction because it is the closest to the denominator 7. Think of it as a pizza that for some reason is cut into seven pieces, if you ate 5 pieces you ate most of the pizza. However if you cut this pizza into 12 slices and only ate 2 well you almost didn't eat much and you can continue this idea of pizza for 15/40 and 8/20.

You can also divide these numbers to see the fraction as decimals but it's not necessary.

Please help I do not get

katen-ka-za [31]

Answer:

(a) 51%

(b) 41%

Step-by-step explanation:

We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.

Looking at this table, we can see that $30+72=102$ girls were asked. So, $102\div200=0.51$ , and $0.51\cdot100=51$ .

We can also see that $30+52=82$ people preferred video games, so $82\div200=0.41$ , and $0.41\cdot100=41$ .

Hope this helped!

How do you do 56 through 58? Thanks to anyone who awnsers!

astraxan [27]

Hello !

56)

$5 {x}^{2} + 8x = - 1 \\ 5 {x}^{2} + 8x + 1 = 0$

$\Delta = {b}^{2} - 4ac \\ = {8}^{2} - 4 \times 5 \times 1 \\ = 64 - 20 \\ = 44$

The value of the discriminant is 44.

57) ∆>0 : there are two solutions.

58)

$x_1 = \frac{ - b + \sqrt{\Delta} }{2a} \\ = \frac{ - 8 + \sqrt{44} }{2 \times 5} \\ = \frac{ \sqrt{11} - 4 }{5}$

$x_2 = \frac{ - b - \sqrt{\Delta} }{2a} \\ = \frac{ - 8 - \sqrt{44} }{2 \times 5} \\ = \frac{ - \sqrt{11} - 4 }{5}$
