### What is one and one-third times four?

1 and 1/3 is 4/3 as an improper fraction, and 4 is 4/1 as a
fraction. Since this is multiplication of fractions, multiply
numerator by numerator, denominator by denominator without common
denominators. 4x4=16; 3x1=3. you now have 16/3, but this is
improper. To get this as a mixed fraction, divide 16 by 3. You get
5 remainder 1, so the answer is 5 and 1/3.

###### Asked in Brain Teasers and Logic Puzzles

### What is the next number in the series 2-5-11-20-32-47?

The next number in the series is 65.
You'll notice that each succeeding number gets a progressive
multiple of 3 added to the previous number in the series. The first
number is 2, and the next number 5 is 2+(3x1). The next number 11
is 5+(3x2), and so forth. To obtain the number following 47, we
simply add to 47 the 6th multiple of 3 (because 47 is the sixth
number in the series), that is, 47+(3x6) = 65.

###### Asked in Chemistry

### What is the purpose of balancing equations?

I don't remember all of the mathematical names, but I do
remember that you need to balance equations so that both
sides will be equal. These are very simple examples but they
will show you that balanced equations are equivalent
to being equal.
Such as: (2+2)=4=(3+1) Both sides equal '4'.
Differing equations on opposite sides of the equal sign
demonstrate that are differing ways to express a certain
figure.
Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal
'5'.
(8) - (3) =5= (4) + (1)
Hope this helps.

### How do you do long division for starters?

Long division is easy once you get the hang of it.
I had trouble with it in the beginning, but then quickly got the
hang of it. Just remember these steps: divide, multiply, subtract,
bring down.
I will solve this equation: 504 divided by 9. (I tried to make
the little upside down L thing as best as I could)

3|504.
DIVIDE...MULTIPLY... How many times does 3 go into 5 evenly?
3x1=3, +2=5. Once. 1__ 3|504 3(<--- 3x1=3, the three in the
solution is put there.) SUBTRACT... 1__ 3|504 -3 =2 BRING DOWN...
1__ 3|504 3 20 (<---bring the zero down next to the two) Start
over with DIVIDE... (how many times does 3 go into twenty?) until
you have nothing else to bring down. There is your answer!! 168
3|504 3 20 18 24 24 0 I really hope this helps!! If not, there are
plenty of math help websites. :)

###### Asked in Science

### How many moles are in 3mg plus 2NH3?

Nitrogen has an atomic mass of 14
Hydrogen has an atomic mass of 1
Therefore, NH3+ has a molecular mass of 17 (14 + (3x1))
Ergo, 1 mole weighs 17g.
1 mol /17g = number of moles in 1g (5.88 x 10-2)
0.0588/1000 = number of moles in 1mg (5.88 x 10-5)
Multiply this by 3, and you have the number of moles in 3mg:
1.764 x 10-4

###### Asked in Algebra

### How do you multiply 3 over 5 and 1 over 2 in simplest form?

When multiplying fractions, just multiply the two top numbers
(3x1), and the two bottom numbers (5x2), to get 3/10 (or 0.3).
Simplest form just means to then reduce the resulting fraction - in
this case it is already reduced. To be reduced, neither number can
have a common factor. For instance, if it was 3/12, both numbers
would have a common factor, and so the simplest form would be
1/4.

###### Asked in Math and Arithmetic, Statistics, Algebra

### How do you solve 1 digit divisors and 3 digit dividends?

Let's say, 315 divided by 3. So, how many times does 3 go into
3? 1 time! So, 3x1=3. Then, Subtract 3-3=0. How many times does 3
go into 0? None! Does 3 go into 1? None! Subtract 1 and 0. You get
one. Does 3 go into 1? None! Does 3 go into 15? Yes! 5 times! So,
do 15-15. You get 0. Your final answer is 105 times.

###### Asked in Math and Arithmetic

### What is Two and a half divided by one and one third equals?

Well, it's simple, to divide fractions like 2 1/2 and 1 1/3,
first you turn them into improper fractions. to change them to
improper fractions multiply the denominator by the whole number and
then add the numerator. 2x2=4+1=5/2. 3x1=3+1=4/3. now you have 5/2
divided by 4/3. now you flip the the second fraction and change the
division into multiplication so it looks like this 5/2x3/4. Now to
solve the problem. 5/2x3/4=15/8. then change it back into a mixed
number by dividing the numerator by the denominator. 15 divided by
8=1 7/8 So two and a half divided by one and one third equals one
and seven eighths

###### Asked in Math and Arithmetic

### How do you get a common denominator between two fractions?

Find the lowest common multiple of the denominators then
multiply the top and bottom of the fractions to get this
denominator.
so for example for:
1/3 + 1/2 the lowest common multiple is 6.
6 = 3 x 2
so 1/3 = 2x1/2x3 = 2/6
and 1/2 = 3x1/3x2 = 3/6
therefore 1/3 + 1/2 = 2/6 + 3/6 = 2+3/6 = 5/6
and it works for much bigger numbers too

###### Asked in Prime Numbers, Composite Numbers

### Is 1823 prime or composite?

You'll have to test whether 1823 can be divided by every number
from 2 up to 42. You can stop there because 43 x 43 is bigger than
1823. You can test only prime numbers between 2 and 42, so 2, 3, 5,
7, 11, 13, 17, 19, 23, 29, 31, 37, 41. 2 is out because 1823 is not
even. 3 is out because 1 + 8 + 2 + 3 is 14, which does not divide
by 3. 5 is out because 1823 does not end in 0 or 5. 7 is out
because 182 - 3x2 = 176, which does not divide by 7. 11 is out
because 182 - 3x1 = 179, which does not divide by 11. Then I run
out of tricks to see if numbers can be divided by other numbers, so
I test with a calculator. Everything gives a fraction. So 1823 is
prime.

###### Asked in Prime Numbers

### How do you explain what a prime number is?

A prime number is a number can't be multiplied with any number
but 1 and itself. For example 3, you can't multiply any numbers but
1x3 or 3x1 to get 3 so it's a prime number. The prime numbers to
100 are 1, 2, 3, 5, 7, 11, 13, 17, 19, ,23, 29, 31, 37, 41, 43, 47,
53, 59, 61, 67, 71, 73, 79, 83, 89, 97. All of the numbers in
between are composite.
