You're super close

4x > 10

To figure out what x is, we divide both sides by 4 so:

x>2.5

4x > 10

To figure out what x is, we divide both sides by 4 so:

x>2.5

treat the inequality as an = sign, so:

4x>11(-1) ~> 4x>10

x>10(divided by 4) ~> x > 10/4

simplifies to:

4x>11(-1) ~> 4x>10

x>10(divided by 4) ~> x > 10/4

simplifies to:

**x > 5/2**

4 divided by 4 is one though

**IH8Studying**)4 divided by 4 is one though

4x/4 > 10/4

Yep, so If we divide 4x by 4, we get 1x, which is the same thing as x

4x/4 > 10/4

x>2.5

You can always leave it as a fraction. You will still get the marks!

is it fine to leave the equal sign there though?

You can leave it as a fraction though - just divide out common factors:

To get this to a decimal, you can multiply by 10, divide, then move the decimal point to divide by 10:

to put things simply, just find a number that both the top and bottom number will divide into when simplifying a fraction and keep doing this until both top and bottom have no other common multiples.

just remember to change the sign back at the end

No problem! Once you get used to algebraic division, this'll be a breeze

The fraction is 10/4 which can be simplified to 5/2 then if you write that as a mixed number it’s 2 1/2 which is the same as 2.5

You need to learn how to do that.

why is it 10/4 and not 4/10?

**IH8Studying**)why is it 10/4 and not 4/10?

So:

10 divided by 4 = 10 / 4

Just replace the 'divided by' with the fraction sign

and the equal sign is what?

seems hard . thanks

why is it 10/4 and not 4/10?

i don’t get the last part whatsoever. i’ll watch a video on it

Here you need to "divide both sides by 4" to get rid of the 4 on the left. So you get

x > 10/4

10/4 means "10 divided by 4". The line in the middle of a fraction means the same as "divided by".
