Step-by-step explanation:
For example, in order to multiply 832,000 by 0.00035, one converts first to scientific notation as follows: (832,000)×(0.00035)=(8.32×10 5)×(3.5×10 −4)=8.32×3.5×10 5×10 −4=29.12×10 1=2.912×10 2 (in scientific notation) or 291.2 (in ordinary notation).
Answer:
Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.
Step-by-step explanation:
The following subset of the real number system can be written in the form
, b≠0.
Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as ![\dfrac{5}{1}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B1%7D)
Terminating Decimals: These are fractions that when converted to decimal numbers have an end.
e.g. ![\dfrac{5}{2}=2.5](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B2%7D%3D2.5)
Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.
e.g. ![\dfrac{8}{11}=0.727272...=0.\overline{72}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7B11%7D%3D0.727272...%3D0.%5Coverline%7B72%7D)
Proper Fractions: These are fractions of the form
where a<b. An examples is ![\dfrac{4}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B4%7D%7B5%7D)
Improper Fractions: These are fractions of the form
where a>b. An examples is ![\dfrac{5}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B4%7D)
Marcie has 41 1/3 feet of packing tape left.
8 5/6 times 2 makes 17 2/3. 59 minus 17 2/3 equals 41 1/3.
So to find a percent of increase you have to put the current number minus previous number(in this case 20-16) over the previous number(16 in this case) and multiply by 100.
So we have 20-16/16 multiplied by 100.
Since 4/16= 0.25,multiplying It by 100 gives you 25.
So the answer is 25%
Answer:
12.5%
Step-by-step explanation:
[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100
[50 - 30] ÷ [ 50 + 30] ÷ 2 × 100
20 ÷ 80 ÷ 2 × 100
0.25 ÷ 2 × 100
0.125 × 100
12.5 %
