How do you write $7$ as a percentage?

Hint: So when we have to write any number into the percent then we just need to do the multiplication of the number by $100$ and adding the percent sign in the end. So by using this we will convert the number into a percentage.

Complete step by step solution:
Here in this question we need to find the value that will be $7$ as a percentage. So for this, we will multiply the number by $100$ and get the value.
On multiplying the number by $100$ we will get the equation as
$ \Rightarrow 7 \times 100$
And on solving the above equation we will get the equation as
$ \Rightarrow 700\% $
Therefore, $7$ as a percentage will be equal to $700\% $ .

Note: Here, we can see that we are having just a number. And we had seen how we could solve it. Now if we have the number in fraction or decimal then also we will do the same process. In that case, we multiply the fraction with $100$ or while in decimal we will multiply it by $100$ . So in this way, we can solve such types of questions.
