Express 0,45 as a common fraction in simplest form

2 answers:

8 0

In order to express 0.45 as a common fraction, all you have to do is first divide 45 to 100. So in order to get the answer to this, you just have to put 45 as the numerator and 100 as the denominator. This will become 45/100. To turn it into its simple form, you have to first ask yourself what is a common divisible number for the two. 5 can be divided by 45 and 100 so 5 can be used. So the final answer, if you make it into simplest form, will be 9/20

If you would like to know what is 0.45 as a common fraction in its simplest form, you can calculate this using the following steps:

0.45 = 45/100

45/100 simplifies to 9/20 (the common factor of 45 and 100 is 5, so you can divide both numbers by 5).

The correct result would be 9/20.

A group of ‘n' friends decided to rent a condominium for a one week vacation in Florida. They decided to share the weekly rent o

Answer:

2m / n² - 2n

Step-by-step explanation:

Given that:

Number of friends = n

Weekly rent = $m

To share rent fee equally :

Each friend will pay : $m / n

If 2 of the friend couldn't make the trip:

Additional amount to be shared by the others = 2(m/n) = 2m/n

Hence additional fee per friend who eventually made the trip:

Additional amount to be shared / number of friend who eventually made the trip

= (2m/n) ÷ (n - 2)

= 2m / n * 1 / n - 2

= 2m / n(n-2)

= 2m / n² - 2n

Of the two bottles shown of sunblock shown, which is the better buy? Explain. Sunblock 1: 4 ounce bottle $8.49 Sunblock 2: 5 oun

Pepsi [2]

8.49/4 = 2.1225

Sunblock 1 costs $2.12 per ounce of sunblock.

10.29/5 = 2.058

Sunblock 2 costs $2.06 per ounce of sunblock.

Sunblock 2 is the better buy because it is cheaper ounce-per-ounce.

Answer:

The graph of the system of equations solves the equation $-\frac{1}{4}$ x + 2 = 2x - 7 ⇒ C

Step-by-step explanation:

Let us revise some important notes about the slope and y-intercept of a line

The form of the linear equation is y = m x + b, where m is the slope and b is the y-intercept

If the line has a positive slope then its direction will be to the right

If the line has a negative slope then its direction will be to the left

The y-intercept (0, b) is the the point of intersection between the line and the y-axis

If the line cuts the y-axis at a point above the x-axis, then b is positive

If the line cuts the y-axis at a point down the x-axis, then b is negative

To solve our question without any calculation, let us find the direction of the slopes and their y-intercepts

∵ The direction of the blue line is to the left

→ That means m in the equation is negative

∴ Its slope is negative

∵ The line intersects the y-axis at point (0, 2)

→ That means b in the equation = 2

∴ The number in the equation is 2

→ Look at the answer we have two answers have negative slope and

y-intercept 2 in the left hand side ⇒ C and D

∴ The equation of the blue line is represented by the left side $-\frac{1}{4}$ x + 2

→ that means the equation of the red line is represented by the right side

∵ The direction of the red line is to the right

→ That means m in the equation is positive

∴ Its slope is positive

→ Only C has a positive slope in the right side

∴ The equation of the red line is represented by 2x - 7

The graph of the system of equations solves the equation $-\frac{1}{4}$ x + 2 = 2x - 7

Another way:

You can solve each equation to find the value of x, then substitute it in one side of the equation to find y , the values of x and y must be (4, 1) as the point of intersection of the two lines in the graph
