# What is the LCD of 2 4 5?

# Why is 2 plus 2 4 not 5?

The reasoning all relates to Einsteins theory of relativity. Whenan apple falls on your head and your like "Where did this comefrom?" well the answer to this question is that …2 plus 2 equals 4not 5. If the answer were to be 5 in this problem it would havebeen orange not an apple. Now subtraction is a complety differentconcept. You see if you did 4 minus 2 wich we all know is 2 youwould fall on the apple not the apple falling on you. Now here is agood way to explain multiplaction: when luke skywalker and themembers of the rockaholics get in a fight luke would whop them tothe ground. So whe you are defeated by a train jedi your dumbnesswould multiply by 6 billion putting you back on level 22 onrunescape. Now when you divide it is like beating world of warcrafton super mega ultra geek squad difficulty. Its so hard no one cando that. In our number system, which is basically the Arabic number system,which may have originally come from India, we give values to howmany of something there is. It could be apples, oranges, computers,iphones, chairs, books, anything... We have a way of counting them.Some early cultures that didn't have this may have recognized oneof something, two of something, or many of something. They may havehad no understanding of two apples and two apples is four apples,they just knew about many apples and didn't think about adding,subtracting, or any other math. To them A bird in the hand reallywas better than two (or more) in the bush. It's all theyunderstood. Some animals are like that. Back to 2+2=4 (or 5). It doesn't matter what we call 2+2. They arejust symbols that represent values and people long ago definedthese symbols to mean these values and everybody else accepted themto mean these values. Arithmetic also has various rules that makethe number system consistent so that it makes sense. We defined the meaning of the numbers we use as 0 1 2 3 4 5 6 7 89, and a bunch of rules about getting bigger number values like204, 75134 and even 4.7*10^52. We all know that 1+1=2 , because that's how we define "2" similarly 1+1+1=3 (so does 2+1 and 1+2 ), and 1+1+1+1=4 (so does 3+1, 1+3, 2+2) and so on. There is a whole lot of number fact and theory about the system andwhy it works. If 2+2 were 5, than so would 3+1=5 and 1+1+1+1=5. But than what would be 1+1+1+1+1? we would have to call itsomething else. Maybe use "4" since it wasn't being used foranything else. It would work just fine as long as everybody knewthe new rules. But they don't, so we are stuck with 2+2=4. which is just fine because if we used 2+2=5, someone might go toanswers.com and ask "Why is 2+2 5 and not 4?"

1/3, 3/4, 5/32, 8/9 The LCD is 288.

# What is the LCD of 3 4 and 5?

The least common denominator is the least common multiple of the denominators. The least common multiple is the smallest number that is multiple of two or more numbers. …3: 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 The LCD of 3, 4 and 5 is 60.

# What is the LCD of 8 and 5?

It is 40

# What is the LCM of 2 3 4 and 5?

The LCM of these numbers is 60.

# What is the LCD of 5 and 6?

5 factors into 1 and 5 6 factors into 2 and 3 Therefore, the least common multiple is 1*2*3*5 = 30 This is what you would use for the LCD, convert the fifths and sixths …into thirtieths.

# What is the LCD of 5 and 10?

Write the multiples of each: 5, 10, 15, 20 10, 20, 30, 40 10 is in each, so it is the answer.

# What is the lcd of 4 and 2 and 6?

I am assuming that 4, 2, and 6 are the denominators of some fractions. That being said. LCD means Least Common Multiple of the Denominators. So you need to find the Least Co…mmon multiple of the Denominators 4, 2, and 6. This means the smallest multiple they have in common. The multiples of each number are listed below: Remember multiples keep going on forever so I'm only listing the first few. 4: 4, 8, 12, 16, 20, 24, 28, 32... 2: 2, 4, 6, 8, 10, 12, 14, 16... 6: 6, 12, 18, 24, 60, 36, 42, 48... Notice that the smallest multiple they have in common is 12. They have other multiples in common like 24, but it isn't the smallest. The LCD of 4, 2, and 6 = 12.
