Example Questions
Example Question #104 : Arithmetic
Divide:
Examine the divisor 0.004. To make this a whole number, the decimal point needs to be moved three places right. Do this to both 0.004 and 320, adding an implied decimal point after the latter first:
Now perform this division:
Example Question #105 : Arithmetic
Evaluate:
First, multiply, ignoring the decimal points:
Put a decimal point after the number:
Since there were five digits total (one per factor) left of the decimal points, move the decimal point in the product left five places, inserting zeroes as needed:
Example Question #106 : Arithmetic
Express 1.14 as a fraction in lowest terms.
The fraction has its last nonzero digit in the hundredths place, so write the number, without the decimal point, over 100. Then reduce.
Example Question #107 : Arithmetic
Express 450,000,000,000 in scientific notation.
To rewrite a very large number in scientific notation:
Write the number with the decimal point after it (it is implied to be at that location).
Move the decimal point left as many places as needed until it follows the first nonzero digit, which here is the four. Count the number of places it is moved - here it will be eleven places.
The number formed is 
Example Question #701 : Hspt Mathematics
Multiply normally and remember that the decimal point is four places from the right.
Example Question #1361 : Ssat Upper Level Quantitative (Math)
Express 
Divide 8 by 15:
The 3 repeats, so the correct choice is 
Example Question #1362 : Ssat Upper Level Quantitative (Math)
Give the decimal equivalent of 
Divide 11 by 18:
The 1 repeats infinitely, so this can be rewritten as 
Example Question #1363 : Ssat Upper Level Quantitative (Math)
Give the decimal equivalent of 
Divide 5 by 27:
The group "185" repeats infinitely, so this can be written as 
Example Question #1364 : Ssat Upper Level Quantitative (Math)
Give the decimal equivalent of 
Divide 7 by 36:
The 4 repeats infinitely, so this can be rewritten as 
Example Question #1 : How To Find Percentage
A watch originally cost $55.00. If it is on sale for 20% off, what is the sale price of the watch?
To solve:
First, find what is 20% of 55 by multiplying:
Then, subtract 20% (11) from the original price:
The final sale price will be $44.00.
