Answer:
1 7/9 ounces
Step-by-step explanation:
The final solution will be 9 parts water and 1 part hydrogen peroxide (so that hydrogen peroxide makes up 1 of 10 parts of the solution).
Then each "part" is (16 ounces)/9 = 1 7/9 ounces.
1 7/9 ounces of hydrogen peroxide must be added to 16 ounces of water to make a 10% solution.
_____
<em>Check</em>
The total amount of solution is 16 +1 7/9 = 17 7/9 ounces = 160/9 ounces. The amount that is hydrogen peroxide is 16/9 ounces, so the fraction that is hydrogen peroxide is ...
(16/9) / (160/9) = 16/160 = 1/10 = 10%
Answer:
12 slides
Step-by-step explanation:
Okay so we know that Val:
takes 1/6 hours to do each slide
has 2hrs
To figure this question out we have to divide fractions.
To divide a fraction you multiply the dividend by the reciprocal of the divisor.
My simple dictionary:
Dividend - The First number in a fractional problem
Divisor - The second number in a fractional problem
Reciprocal - a fraction flipped upside down so that the numerator is now the denominator. For example 3/2 = 2/3
Now that that is done let's look at the problem.
We have to divide 2 by 1/6 or multiply 2/1 by 6/1
To multiply a fraction we just multiply numerator by numerator and denominator by denominator.
2 x 6 = 12
1 x 1 = 1 (duh)
So, in conclusion, Val can create 12 slides in 2 hours :D
that was some really explicit stuff .-.
Answer:
Amina practices the piano for 54 minutes each week.
Step-by-step explanation:
45% * 120min = 0.45 * 120min = 9/20 * 120min = 9 * 6min = 54min
