How many fifths are the in 60/100
tankabanditka [31]
In order to calculate that, we need to divide it by 1/5 as follows:
60/100 / 1/5

We can re-write it as: 60/100 * 5 = 6/10 * 5 = 30/10 = 3

So, there are "3" 1/5ths in 60/100

Hope this helps!

guajiro [1.7K]
#1) x-8= -12
#2) 15+k= 2
#3) x/-7= -20
#4) (5/8)(x)= -20

The / in #2 means to divide and the ( ) mean to multiply

What is the slope of the line passing through the points (−3, −5) and (−1, −6)?
Virty [35]

Answer:

The slope of the line passing through the points (−3, −5) and (−1, −6) is -\frac{ 1 }{ 2 } (-0.5)

Step-by-step explanation:

Equation of a straight line:

y = mx + b where m is the slope and b is the y-intercept

(x1, x2) and (y1, y2) : (−3, −5) and (−1, −6)

Calculating Slope (m).

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

m = \frac{ (-6) - (-5) }{ (-1) - (-3) }

m = \frac{ -6 + 5 }{ -1 + 3 }

m = -\frac{ 1 }{ 2 }

we can take this a step further by finding the equation:

Now putting value of m in equation (i)

y = -0.5x + b

Calculating Y-intercept (b).

Lets choose the first point, (-3,-5) for calculating y-intercept:

y = mx + b

-5 = -0.5(-3) + b

-5 = 1.5 + b

-6.5 = b

b = -6.5

Now putting value of b in equation

y = -0.5x + -6.5

Choose the fraction that has not been reduced to simplest form 19/3810/1921/3415/18
lozanna [386]

19/38 and 15/18

Explanation:

19/38 can be reduced as there is a factor other than 1 that can divide without a remainder. Factor is 19

It can still be reduced because 19*2 = 38

19/38 = 1/2

10/19 cannot be reduced as there is no factor other than one to divide without a remainder

21/34 cannot be reduced as there is no factor other than one to divide without a remainder

15/18 can be reduced as there is a factor other than 1 that can divide without a remainder.

The factor is 3

15/18 = 5/6

Fraction that has not been reduced to simplest form are 19/38 and 15/18
