Estimate 40% of 20 equals
2 answers:
40% of 20 equals 8.
First, we need to think that 20 is our 100%.
Let's make the variable v as the value we're looking for.
20/v = 100/40
We need to multiply both sides of the equation by v.
(20/v) * v = (100/40) * v
Now, we're left with 20 = 2.5x
We need to divide both sides of the equation to isolate the variable x.
20/2.5 = 2.5x/2.5
8 = x
Our final answer is 8.
40% of 20 is 8
8 is the answer

length of the rectangle = 2w+3
width of rectangle = w
area = L*W
