Answer: 5
Explanation: You must first turn the percentage into a decimal then
0.5% of $1000 is what?
multiply. so 0.5% implies to divide this by 100 or 0.5/100 = 0.005
(1000) =5
0.25 What is 1/4 as a decimal?
Correct answer: 86.5x107
Explanation:
What does the operation ask us to perform?
(0.000034)-1 x (0.000034)-1
Simplify expression in parenthesis:
(34x10-6)-1 x ( 34x10-6)-1 = 34-1x 34-1 x 10-6(-1) x 10-6(-1)= 34-2 x
(0.000034)-2
1012
which is also the same as.......
1/342 = 1/1156 = 8.6505 x 10-4 or 0.00086505
now multiply this times 1012 and we get...
moving the decimal point 12 places to the right.
8.6505 x 108
, Correct answer: 5 (10-5)
Explanation:
Use powers of 10 for the numerator and then divide.
0.00045/9
(45x10-5)/9
45/9 = 5 (10-5)
0.50 What is 1/2 as a decimal?
Correct answer: 0.00055
Explanation:
This is out of 100, so we can either perform long division of
0.055/100 or use the factor of 10
0.055% 55x10-3(10-2)
55x10-5
0.00055
10-2=1/100
0.0068 0.002 x 3.4 = _______.
Answer: 3.14x10-13
Explanation:
Simplify the expression in parentheses first;
(68 x 10-6)3
(0.000068)3 When raising an exponent to any power, multiply that power to
each of the items powers in parenthesis.
683x10-18
Any time that there is a negative exponent, it indicates that the item
is in the denominator, and the exponent then becomes positive
683/1018
0.75 Change 3/4 into a decimal.
, Correct answer: 39
Explanation:
Turn the numerator and denominator into a factor of 10.
78 x 10 -5 ÷ 2.0 x10-5
0.00078/0.00002
Divide 2 into 78 = 39
Subtract the numerator exponent from the denominator exponent:
10 (-5 -(-5)) = 100 = 1
39x1 =39
Correct answer: 12%
Explanation:
0.120 To convert any number to a percent, always multiply by 100, or
remember to move the decimal point two places to the right.
12%
Answer: 0.00104
Explanation: To make this division easier, 0.245 can be written as
0.245/ 234
245 x 10 ^-3 (10 to the power negative 3), then perform the
division.
Answer: 0.096
Explanation:
The best way to tackle this problem is to first turn each number
into a factor of ten, then divide the numbers.
0.000567/0.00589
(567 x 10-6 )/(589 x10-5 )
Long divide 589 into 567 and then use the rules of exponents for
the factors of 10, 10-6-(-5) = 10-1
0.6666 Change 2/3 into a decimal.

1,760 1 mile = _______ yards.
1 cup = ____ ounces 8
1 foot = ____ inches 12
1 foot = 12 inch
1 foot is how many centimeters? 1 inch = 2.54 centimeters
Therefore, 1 foot = 12 x 2.54 = 30.48 centimeters
