How do I simplify a fraction? For example if the question is 7 1/5 divided by 2 2/15 what would I do to simplify?

1 answer:

3 0

7 1/5:
Multiply the denominator and the whole number: 7*5 = 35 and then add the numerator: 35+1= 36/5. Then, do this for the following fraction, the improper fraction value of 2 2/15 is 32/15.
Now we need 36/5 & 32/15 to have common denominators so that we can simplify it a little less complicated.

For Instance,

36/5*3= 108/15

Now we divide, (108/15)/(32/15)
108/32= 3.375 = 3 3/8

Answer is 3 3/8.

Hope this was easy to understand!

Question 2 of 10<br> How many solutions are there to the equation below?<br> 11x + 25 = 7x + 15

Irina18 [472]

One solution
11x + 25 = 7x+15
-7x -7x

4x+25=15
-25 -25

4x= -10
————
4

x= -10/4

-10/4 simplified is -5/2

so there is one solution where x=-5/2

Between 1989 and 1998, the population of smalltown, USA ( in thousands) can be modeled by f(x)=.24x^2 -0.96x + 4, where x=0 repr

maks197457 [2]

Just use derivatives:

f'(x)= .48x-.96 = 0, x = 2, since the coeff of x^2 is +, this is a minimum

x=0 1989, so x = 2 is 1991! :)

Membership to two different clubs are represented by the equations below. The x-value represents the number of months dues are p

mestny [16]

It would take 2 months for the membership of both clubs to be the same

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

The standard form of a linear equation is:

y = mx + b

Where m is the rate of change and b is the y intercept

Let y represent the total cost of dues over x months, hence given that:

y = 3x - 5 (1)

Also:

4x - 3y = 5

y = (4x - 5)/3 (2)

For the membership of both clubs to be the same:

3x - 5 = (4x - 5)/3

9x - 15 = 4x - 5

x = 2

It would take 2 months for the membership of both clubs to be the same

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 50 feet cubed. A cylinder with height h a

Arada [10]

Answer:

Volume of the sphere is 66.67r/h

Step-by-step explanation:

Hello,

Volume of a sphere = ⁴/₃πr³

Volume of a cylinder = πr²h

The volume of the cylinder = 50ft³

But the cylinder and sphere both have the same radius and height

Volume of a cylinder = πr²h

50 = πr²h

Make r² the subject of formula

r² = 50/πh

Volume of a sphere = ⁴/₃πr³

Put r² into the volume of a sphere

Volume of a sphere = ⁴/₃π(50/πh)r

Volume of a sphere = ⁴/₃ × 50r/h

Volume of a sphere = ²⁰⁰/₃ r/h

Volume of a sphere = 66.67r/h

The volume of the sphere is 66.67r/h

Answer the questions please

kirill115 [55]

2) 1/16

3) 25/3 or 8 and 1/3

4) to find the reciprocal of 4 we must make 4 a fraction. Simply add a one as the denominator and then switch as you would usually do when finding the reciprocal.

4 = 4/1 = 1/4

Answer : 1/4

5) first, let's convert 4 5/8 into a improper fraction.

4 5/8 = 37/8

Now let's find the reciprocal of that number...

Answer : 8/37

6) 5/8 ÷ 2/3 does equal 15/16

To check, well do the inverse operation.

The opposite of division is multiplication.

Answer : d

7) 6

8) 13
