The total cost will be $56 because 3 x 8 = 24 so then you multiply 7 x 8 = 56.
You would put it up into proportions so 33 over 55 equals x over 100. Then you would cross multiply so 55x=3300. Then you would divide 3300 by 55 and get 60%.
Approximately 1.143 L of peroxide should be added to the original solution.
Olivia needs 15 yards of ribbon.
2.5x18=45 feet
divide 45ft by 3 to see how many yards that would be.
45/3=15
Hope that I helped
Whole numbers with more digits are greater than whole numbers with fewer digits.
Unless there is a decimal making the number have more digits then the answer to the blank would be greater than.
