One less than quotient of four and a number x

If all you want is just how this is written, then the answer is

That's the way it reads. However you may have meant

We cannot exactly tell from the wording what is meant. I would choose the first one, if this multiple choice. I would note the ambiguity if a person is doing the marking.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
