Question

35% is 7 out of what number?

Answer 1

We already have our first value 7 and the second value 35. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

`\sf \longmapsto 7 = 35\% * \: Y`

`\sf \longmapsto \: 7 = (35)/(100) * Y`

`\sf \longmapsto \: Y = 7 * (100)/(35)`

`\sf \longmapsto \: Y=7×100÷35`

`\sf \longmapsto \: Y = 20`

Answer 2

The number is 20.

Step-by-step explanation:

In this question, it is said that 35% of a number is equal to 7, then what is that number?

So, let the number be x.

Now, according to the question :

`\begin{gathered} \begin{array}{l} \quad{\dashrightarrow{\sf{35 \% \: of \: x = 7}}}\\\\\quad{\dashrightarrow{\sf{(35)/(100) \: of \: x = 7}}}\\\\\quad{\dashrightarrow{\sf{(35)/(100) * x = 7}}}\\\\\quad{\dashrightarrow{\sf{(35 * x)/(100) = 7}}}\\\\\quad{\dashrightarrow{\sf{(35x)/(100) = 7}}}\\\\\quad{\dashrightarrow{\sf{x = 7 * (100)/(35)}}}\\\\\quad{\dashrightarrow{\sf{x =(700)/(35)}}}\\\\ \quad{\dashrightarrow{\sf{x = \cancel{(700)/(35)}}}}\\\\ \quad{\dashrightarrow{\sf{x =20}}}\\\\ \quad{\star{\underline{\boxed{\tt{\red{x =20}}}}}} \end{array}\end{gathered}`

Hence, the number is 20.
