The difference between a hundred and a number is four times that number

Mathematics
1 answer:
damaskus [11]4 years ago
5 0

<u>Answer:</u>

20

<u>Step-by-step explanation:</u>

We know that the difference between a hundred and a number is four times that number.

So assuming the number to be x, we can write the difference between a hundred and a number as <em>100 - x </em>and four times that number as <em>4x</em>.

So by combining these together, we get:

100 - x = 4x

100 = 5x

x = 100/5

x = 20

Therefore, the unknown number is 20.
