You're super close

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: x > 5/2

4 divided by 4 is one though
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

is it fine to leave the equal sign there though?

oh i just don’t know how to divide numbers that don’t go into each other

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

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.

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.

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

2/5 is what i would’ve put

The fraction sign is basically the same as the divide sign

So:
10 divided by 4 = 10 / 4

Just replace the 'divided by' with the fraction sign

4x > 10

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".
