Answer: 40 percent of 4 is 1.6
Step-by-step explanation: 40 x 4 / 100 = 1.6. You could also look at it like this, two simple equations:
1) 4=100%
2) x=40%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
4/x=100%/40%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 40% of 4
4/x=100/40(4/x)*x=(100/40)*x - we multiply both sides of the equation by x
4=2.5*x - we divide both sides of the equation by (2.5) to get x
4/2.5=x
1.6=x
x=1.6
now we have:
40% of 4=1.6
I hope this helps you!
