Why is 0.04 is 1/10 of 0.4

Answers

Answer 1

Answer: is in mathematics means the equal sign
of in mathematics means multiplication

So translating that sentence into an algebraic expression, it would be:

0.04 = 1/10 x 0.4

And that statement is true! Because when you divide a number by 10, you move the decimal over to the left one time.

What is the greatest common factor of 9 and 11

Answers

ANSWER:

The Greatest common factor (G.C.D) of 9 and 11 is 1

SOLUTION:

Greatest common factor (G.C.D) is the highest number which is factor for both the given numbers.

Here the numbers are 9 and 11.

We can find the Greatest common factor (G.C.D) of 9 and 11 using prime factorization method.

In prime factorization method, each number is written as the multiple of their prime factors, after that, on comparison we can find the Greatest common factor (G.C.D).

The prime factorization of 9 = $3 * 3 * 1=1 * 3^(2)$

The prime factorization of 11 = $11 * 1 = 1 * 11$

We can observe that, greatest common factor for both 9 and 11 is 1.

Hence Greatest common factor (G.C.D) of 9 and 11 is 1

The GCF of 9 and 11 is 1

What is half of 1 plus 500 dived by 2

Answers

half of 1=1/2=0.5
plus 500
500+0.5=500.5
divide by 2
500.5/2=250.25

Half of 1 = .5 or 0.50
500.5 ÷ 2 = 250.25

45 mph to 25mph as a fraction in lowest terms.

Answers

If you have a scientific calculator, enter in 45/25. You will get a decimal, but on some, if not most, calculators, it can convert it to fractions for you.
You will get: 9/5 mph.
Mixed number: 1 and 4/5

You have to divide 45/25 or used the calculator but if you want the answer to be as a fraction in lowest terms you have to simply 45 and 25 by 5

45 /25 divide by 5 will be= 9/5 if you simplify it again will be 1 and 4/5.
