Answer:
x = 50
Step-by-step explanation:
Let x be the original number.
This question can be expressed as:
0.4x = 20
0.4 of the original number is 20.
Now, we can directly solve for x:
4x = 200
8
40 times 0.20 is 8.
You can also use 40 percent of 20, which is also 8, but the original is easier to comprehend.
