Convert both to improper fractions, divide, then simplify.

3 3/4 is 15/4, 1 1/8 is 9/8. Dividing 15/4 by 9/8 is 120/36. Reducing to lowest terms gives 10/3, which is 3 and 1/3.

SOURCE: If a thread of length 22units can be divided in 7

It's all due to the "base" in which you count,
and your definition of "exactly" divided,
right down to each of the 7 pieces being the *SAME* number of atomic particles, placed end-to-end.

If you used "base-seven", then 22 (base-ten) would be written as 31 (base-seven). So, 31 (base-seven) divided by 7 (base-7) would be '3.1' (3 times 1*7**0 + 1/7**1), where '3.1' (base-seven) is *NOT* an irrational number.

SOURCE: Is it possible to have

Yes, it's possible because not all numbers are multiples of ten. For example if you divide 63 by 30 (which is multiple of 10) you get 2 and remainder 3 (because 63=2*30+3).

Use compatible numbers to find two estimate that the quotient is between 1,624 divided by 3


Hi Tammy:
Here's what I would do.
1) 1500 divided by 3 equals 500
that would leave 124
2) 120 divided by 3 equals 40
That leaves 4
3) 4 divided by 3 equals 1
with 1 remaining.
putting the quotients together you get 541
with 1 remaining.
All can be done mentally with no calculator and basic multiplication tables that most school children memorize.

Is this what you were looking for?
Cheerfuls.

How to divide 1 2/3 by 3


First make 1 2/3 into a mixed fraction and then divide it by 3.
To make 1 2/3 into a mixed fraction, multiply the whole number, in this case, 1, by the denominator (the bottom number) and then add the numerator (the top number). Thus, we get (1*3+2)/3 or 5/3. Now we have to take 5/3 and divide it by 3. I was taught that in this case, dividing by 3 is the same as multiplying by 1/3. 5/3 x 1/3 = 5/9.

If you have access to a calculator you can always check this. On the calculator, do 2 divided by 3 and add 1. Now take that answer and divide by 3. Write down this answer. Now take 5 and divide by 9. Write down this answer. They should be the same.

Good luck.

How do i factor numbers on a ti-30xs calculator


This calculator does not have a key that you can use to find the prime factor of an integer.
You can however use the calculator to find the factors
1. If number is even divide it by 2
Keep dividing by 2, while keeping track of how many times you divided by 2.
If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5
2. Now try dividing by 3, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.
If you divided 4 times by 3, your second factor is 3^4
3. Divide by 5, until you can't any more. Keep track of the number of times you divided by 5.
4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

Example: 23100
Division by 2
23100/2=11550 ---------> 1 division by 2
11550/2=5775 ----------> 2 divisions by 2
Note that 5775 is not divisible by 2. No more divisions by 2.
First factor is 2^2


Division by 3:
5775/3=1925 ----------> 1 division by 3
1925/3=641. 66667 Not an integer. No more divisions by 3.
2nd factor is 3^1

Division by 5 (number ends in 5)
1925/5 =385 -------> 1 division by 5
385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)
3rd factor is 5^2

Division by 7
77/7=11 --------> 1 division by 7, and no more
4th factor is 7^1=7

Division by 11
11/11=1
5th factor is 11^1=11

Assembling the factors 2^2, 3^1, 5^2, 7, 11
Prime factorization of 23100 is
23100=(2^2)(3)(5^2)(7)11

How to divide mixed numbers


Since you didn't give any mixed numbers, I'll first divide one fraction by the other.

1/3 divided by 13/9 is the same as 1/3 multiplied by 9/13. Multiply 1 by 9 to get 9, multiply 3 by 13 to get 39. The result is 9/39, which reduces to 3/13.

How to divide mixed numbers?


Probably the simplest is to convert both numbers to improper fractions then divide.
Some calculators can work with fractions. With one of those, simply enter the first mixed number, then divide by the other.

Convert 13/5 to a whole number


13 divided by 5 is 2 with a remainder of 3, so the mixed number would be 2 3/15 which reduces to 2 1/5.

Mixed numbers


Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer
