Explain how you can tell that 31/33 is in the simplest form

Answers

Answer 1

Answer:
In order to simplify a fraction, you need to divide the top and bottom
by the same number. That means that the top and bottom must have
a common factor ... you have to find that first, before you can start
simplifying. Maybe that's why they teach common factors before they
teach simplifying fractions.

Anyway, I can take one look at this fraction and see that the top and
bottom have no common factor. In fact, the top number ... 31 ... is a
prime number, so it doesn't have any factors at all, except ' 1 ' and itself.

And that's how I can tell that the fraction is in the simplest form.

Answer 2

Answer: Simplest form is a form in which we cann't divide the fractions digits like 31/33

The sum of three consecutive even numbers is 78. What is the first number

Answers

even consecutive numbers are 2 apart
(2,4,6, example)
so they are
n,n+2,n+4
their sum is 78
n+n+2+n+4=78
3n+6=78
minus 6
3n=72
divide 3
n=24
smallest is 24

3x + 3 = 78
3x = 75
x = 25
So the three numbers are 25, 26, and 27.

8 meters increased by 25% is how many meters.

Answers

First find 25% of 8
multiply 25/100 or 0.25 by 8. you get 2. This is the same as dividing 8 by 4 (or
8 x 1/4).
Then add that 25%, which is 2, to 8 meters and you get 10 meters
easy peasy :)

hope this helps

Since 25% is 1/4 of 100%, then you do 8/4 and you get 2 and then you do 2 + 8 = 10.
