32 is 40% of what number?
I am brushing up on math that I haven't done in years. Could someone please explain this step-by-step to remind me how to do this kind of problem properly? Thank you!
using algebra:
let the number be x
.40x = 32
x = 32/.40 = 80
using the "unit" method
40% ----> 32
1% ------ 32/40
100% -----> (32/40)(100) = 80
Thank you very much!
To find out what number 32 is 40% of, we can follow these steps:
Step 1: Set up an equation:
Let the unknown number be x.
We know that 32 is 40% of x, so we can write it as:
32 = 0.40 * x
Step 2: Solve for x:
To isolate x, we can divide both sides of the equation by 0.40:
32 / 0.40 = x
Step 3: Calculate the answer:
Evaluating the division, we get:
x = 80
Therefore, 32 is 40% of 80.
