A 12 ounce mixture of window cleaner is 4% alcohol. How many ounces of the mixture is alcohol

1 answer:

6 0

0.48 ounce is alcohol
Because you have to divide 100% from 12 ounces which is equivalent to 0.12 ounces for 1% now you will have to multiply 0.12 x 4% WHICH is 0.48 ounce

How to estimate

monitta

4 3/5 ≈ 5
1 1/5 ≈ 1

(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers

_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5

That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."

He still has half way more to go because 3/8+1/8=4/8 or 1/2. So he has 1/2 of the way left to walk.
