Download To compare fractions you must find a common denominator. Example:

FL.MA.6.A.5.1
Use equivalent forms of fractions, decimals, and percents to solve problems.
FL.MA.6.A.5.2
Compare and order fractions, decimals, and percents, including finding their approximate location on a number
line.
FL.MA.6.A.5.3
Estimate the results of computations with fractions, decimals, and percents and judge the reasonableness of the
results.
Using Fractions to Compare:
To compare fractions you must find a common denominator.
Example:
Step 1: Find the LCM of the denominators by listing out the multiples.
Step 2: Choose the lowest common multiple.
Step 3: Multiply using the property of one to change your denominator to the LCM you
found in step 2.
Step 4: Once the denominators are the same, the larger the numerator, the larger the
fraction.
-----------------------------------------------------------------------------------------------------------------------------Compare Numbers (Order and compare fractions, decimals, and percents.)
Example: Put the following numbers in order from least to greatest.
1
8
0.25
3
16
50%
In order to compare these numbers, you should change them all into decimals.
 To change a fraction into a decimal, divide the denominator into the numerator:

1
= 8 1 Remember to add a decimal point and zero in order to divide. 8 1.0
8
3
= 16 3 or 16 3.0
16
To change a percent into a decimal, simply remove the percent sign and move the decimal point 2 places to the
left: 50% = .50
5% = .05
3
= 0.1875 or about 0.19 50% = 0.50 and the decimal 0.25

Order from least to greatest would be
0.25 0.50

So

= 0.125 or about 0.13

Order from greatest to least:

How would you solve a question like this: Which of the following numbers represents a value greater than 1?
1
5
0.75
0.10

2
For decimals to be greater than 1, the whole number must be greater than 0. Remember, the whole number is before the
decimal point. 0.75 and 0.10 both have whole numbers of 0, so they are both less than 1.
For fractions to be greater than 1, the numerator must be larger than the denominator (improper fraction.) Since 1/5 is proper,
it is less than 1. Since 3/2 is improper, it is greater than 1. Therefore, the answer is to the question above is 3/2.

----------------------------------------------------------------------------------------------------------------------------------Percent of a Number
To find the percent of a number, simply multiply the decimal form of the percent by the number.
25% of $36 = 36x.25=
36
So, 25% of $36 is $9
x .25
180
720
9.0 0
This type of question will most likely be in the form of tax, tip, interest, or a sale price. Find the percent of the given amount by
multiplying. Then make sure you answer the correct question. Read the question carefully!!!!!
A sweater originally costs $36 but was on sale for 25% off. How much money will you save on the sweater?
Find 25% of $36 = $9. The answer is $9.00
However: A sweater originally costs $36 but was on sale for 25% off. What was the sale price of the sweater?
Find 25% of $36 = $9. Then you need to subtract that $9 from the original $36 to get $27. The answer is $27.00
Try these on your own:
1) You had dinner at a restaurant with your family. The meal cost $28.00. Your mother gave a 20% tip. How much tip did
she leave?
2) You had dinner at a restaurant with your family. The meal cost $28.00. Your mother gave a 20% tip. How much was the
total bill for the dinner?
----------------------------------------------------------------------------------------------------------------------------------Reasonable Estimates
What is a reasonable estimate for the product of 3.75 x 2.19?
Step 1: Round each number to the nearest whole number: 3.75 ≈ 4 and 2.19 ≈ 2
Step 2:Multiply the rounded numbers: 4x 2 = 8
Step 3:So, a reasonable estimate for 3.75 x 2.19 is approximately 8.
Try these:
1) What is a reasonable estimate for the quotient of 892  3.6?
2) Is 347.8 a reasonable estimate for 9.4 x 3.7? Why or why not?
