Find the difference between8/15 and 2/3 Show all calculations in your final answer.

kherson [118]

Answer:

$\frac{8}{15}-\left(\frac{-2}{3}\right)=\frac{6}{5}$

Step-by-step explanation:

Let the value of a number 'a' be = 8/15

Let the value of a number 'b' be = 2/3

The difference between the two numbers can be calculated by subtracting the numbers

$a-b=\frac{8}{15}-\left(\frac{-2}{3}\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$=\frac{8}{15}-\frac{-2}{3}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}$

$=\frac{8}{15}-\left(-\frac{2}{3}\right)$

$\mathrm{Apply\:rule}\:-\left(-a\right)=a$

$=\frac{8}{15}+\frac{2}{3}$

$\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}$

$=\frac{8+10}{15}$

$=\frac{18}{15}$

$\mathrm{Cancel\:the\:common\:factor:}\:3$

$=\frac{6}{5}$

Thus,

$\frac{8}{15}-\left(\frac{-2}{3}\right)=\frac{6}{5}$

Aadya and Ethan like playing with remote-control cars. There's a straight track at the

e-lub [12.9K]

The distance between the two cars is now 320 yards.

<h3 /><h3>Distances</h3>

To determine what is the distance between the two cars now if they did not collide the following calculation must be performed:

500 - (500 - 405) - (500 - 415) = X
500 - 95 - 85 = X
500 - 180 = X
320 = X

Therefore, the distance between the two cars is now 320 yards.

The price of a computer was decreased by 20% to £136. What was the price before the decrease?

Contact [7]

Answer:

£ 170 .

Step by step explanation :

Given that the price of a computer was decreased by 20% to £136. And we need to find the Original price before the decrease. So , let the earlier price be x ,

Decrease in 20 % :-

⇒ Decreased price = 20% of x

⇒ Decreased price = 20/100 × x

⇒ Decreased price = x/5

New price :-

⇒ New price = x - x/5

⇒ New price = 5x - x/5

⇒ New price = 4x/5.

But its given £ 136 , So

⇒ 4x/5 = £ 136

⇒ x = £ 136 * 5/4

⇒ x = £ 170

<h3>Hence the Original price was £ 170 .</h3>
