What is the rule for dividing by 3?
If the sum of the digits in a number is divisible by 3, then the original number is divisible by 3.
Is the square of a number always larger than the original number?
Yes, unless the original number is 0 or 1.
What is a positive number divided by a negative number?
when you are dividing 2 numbers with the same sign the answer is ALWAYS positive but when you are dividing 2 number with opposite signs the answer is ALWAYS negitive. the same is true with multiplication also
How does pick a number double it add 10 divide it by 2 then minus it by the number you first thinking of Its always going to be 5 Always work?
This mathematical operation involves a series of steps that ultimately simplifies to a specific result, which is always 5. The initial step of picking a number, doubling it, adding 10, and dividing by 2 is essentially a way to manipulate the original number algebraically. Subtracting the original number at the end cancels out this manipulation, leaving you with a constant result of 5 regardless of the initial number chosen. This phenomenon occurs due to the properties of algebraic operations and the specific sequence in which they are performed.
What happens when you divide number by a number between0and1?
Dividing by a number (between 0 and 1) will result in a higher magnitude number than the original. If the number was positive, then it will be a bigger number, if the number was negative, the answer will be 'more negative'
Why does dividing by a number less than zero make the original number bigger?
Dividing by a negative number reverses the sign of the quotient. For instance, if you divide a positive number by a negative number, the result is negative, which is smaller than the original positive number. Conversely, dividing a negative number by a negative number yields a positive result, which is larger than the original negative number. Hence, the operation effectively increases the value of the original number when the divisor is negative.
What is always the result of dividing an integer when the divisor is nonzero?
A rational number is always the result of dividing an integer when the divisor is nonzero.
What are the effects of dividing a rational number by a number between zero and one?
a decrease in value of the original number, or divisor.
When dividing a fraction is the quotient always a whole number?
Not necessarily.
What is the rule for dividing by 3?
If the sum of the digits in a number is divisible by 3, then the original number is divisible by 3.
Mitosis occurs in living things when a cell divides to produce two cells compared to the oringinal cell how many chromomes are in each of the resulting cells?
In humans, mitosis is a diploid cell dividing to create two diploid daughter cells. Meiosis is a diploid cell dividing twice to produce four haploid gametes.
Why When dividing a number less than 1 the answer is bigger than the original?
Because you are multiplying by the inverse, which is bigger than the original fraction.
Why is a negative number times a negative number always equal a positive number?
because you are dividing with same signs
Is the square of a number always larger than the original number?
Yes, unless the original number is 0 or 1.
What is a positive number divided by a negative number?
when you are dividing 2 numbers with the same sign the answer is ALWAYS positive but when you are dividing 2 number with opposite signs the answer is ALWAYS negitive. the same is true with multiplication also
Can number 1 be used in a factor tree?
No. One isn't prime. Dividing by one doesn't help, because it leaves you with the original number.
How do you change a rational number to a decimal?
Any fraction is a rational number and by dividing its denominator into its numerator will produce a decimal number as for example 3/4 = 0.75
