Without calculating, is 1 1/6 × 4/5 less than or greater than 1 1/6. Is the product less than or greater than 4/5? Explain your reasoning

Answers

Answer 1
Answer: 1 and 1/6 is 1.16666666 (1 divided by 6) and if it is multipled by 1 it is still 1.1666666, so if it is multipled by a number less than 1 it will be less than the original number (multiply it by a half and you half it, this is multiplied by 0.8)

What is the difference between a prime number and a complex number?

Answers

"Prime"and "complex"are not opposites. If a number is a prime, then it has
exactly two factors ... ' 1 ' anditself. If it has any more factors, then it's not
a prime number, it's a"COMPOSITE" number.

(If a number is not a 'complex' number, then it's a REAL number.)

A Prime number is a number is a number which cannot be divided by any numbers except for itself and one to give an integer

A Complex Number is any number containing Real and Imaginary parts (Imaginary= √(-1)=i

Hey there CR7

Rounding Question::

Let me give you an insight of how and when to round using numbers:

You round down when the number in the selected column is below 5.

You round up when the number in the selected column is 5 or above 5.

So; in your case; we have to round to the nearest ten -

How to calculate square root?

Answers

To calculate the square root, you can either use the √symbol on a calculator or you can manually find it using Prime Factorization. For non-perfect squares, Prime Factorization is the way to go. 
 
The first two steps work for solving large perfect squares as well.

1. Divide your number into perfect square factors.

2. Take the square roots of your perfect square factors. 

3. If your number doesn't factor perfectly, reduce your answer to simplest terms. 

4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be. 
ie.  √(63)       you know that 7^2 =49 and 8^2 = 64,  so you can estimate that the √(63) would be between 7 and 8 but closer to 8.

5. Alternatively, reduce your number to its lowest common factors as your first step. Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).
ie.  
√(45)
 =  √(9*5)
 = √(3*3*5)
 =   3 √(5)
