How do I find a least common denominator? ​

Mathematics

Answer:

Below.

Step-by-step explanation:

You can find this by first finding the prime factors of the numbers.

For example, find the LCD of 12 and 16:

12 = 2 * 2 * 3

16 = 2 * 2 * 2 * 2

There are 2 pairs of 2's in the list so only 2 of these four are included in the calculation. All other factors are included.

The LCD is:

2 * 2 * 2 * 2 * 3

= 16*3

= 48.

Find the LCD of  3 and 6

6 = 2 * 3

3 = 3

- so only one of the 3's is included:

LCD = 2*3 = 6.

Answer:

to find the least common denominator list out the multiples of both denominator until you find the smallest multiple that is shared by both

4: 4,8,12,16,20,24,28,32,

7:14,21,28,35,

because 28 is the first shared multiple of 4 and 7,it most be the least common denominator for these two fractions.

Step-by-step explanation:

5m + 7/2 = -2m + 5/2
5m + 2m = 5/2 - 7/2
7m = -1

Doug digs a hole that is 1.7 feet below ground level. He plants a bush that is 3 2/10 feet tall from the bottom of the root to t
ioda
1.7 = 1 7/10 = 17/10
3 2/10 = 32/10

32/10 - 17/10 = 15/10 = 1 5/10 = 1.5 feet above ground

Item 16
alexdok [17]

Answer:

Step-by-step explanation:

Given that the dresser is in shape of a rectangular prism

Note that, a rectangular prism has a shape of a cuboid

So, area of the rectangular prism is same as area of a cuboid

A = (2LB + 2LH + 2BH)

Where

L is length

B is breadth

H is height

Then, given the dimension of the rectangular prism to be

2ft by 2ft by 6ft

Then, you can assume that,

Length L = 2ft

Breadth B = 2ft

Height H = 6ft.

NOTE: you can take you assumption anyhow, there is no standard, you will get the same answer.

Then,

A = (2LB + 2LH + 2BH)

A = (2×2×2 + 2×2×6 + 2×2×6)

A = (8 + 24 + 24)

A = 56 ft²

The total surface area of the dresser is 56ft²

20 points<br> How do you convert mass to volume without density?
kherson [118]

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
