Answer 1

Expression: There are
`(7n)/(3)` fruits in the box

Numeric answer: There are 49 fruits in the box

Step-by-step explanation:

To get the expression, we need to write out all the details we were given by the question this includes the variables, and the quantities they represent.

Number of apples in the box = n

let the total number of fruits =
`x`

we are given that
`n=(3)/(7) x`

Hence, to get the total number of fruits in the box, we make x the subject of formula which is

`x=(7n)/(3)`

If n = 21, we will have that

`x=(7 * )/(3)= 49 fruits`

Hence, there are 49 fruits in the box
