Answer 1

When a number is decreased by 40% of​ itself, the result is 60. What is the​ number?

Let the number be x.

Percent may be 40% or 0.40 or 40/100.

"of" usually means multiply

"decreased" means subtract.

So --

x - 0.4x = 60

(0.6)x = 60

x = 100

Note: checking your result is a good practice.
