Proper and Improper Fractions
Fractions
Proper Fractions
Bottom (denominator) is greater than the top (numerator) number. So its value will be below one.
Examples:
1/4 = 0.25
5/16 = 0.3125
11/32 = 0.34375
3/8 = 0.375
7/16 = 0.4375
1/2 = 0.50
9/16 = 0.5625
5/8 = 0.625
11/16 = 0.6875
3/4
13/16
7/8
15/16
Improper Fractions
Bottom (denominator) is greater than the top (numerator) number. So its value will be greater than one.
Examples: 1/4, 1/10, 4/5, 9/10, 234/300
Improper Fractions
Same as above, but using the metric system, and vice versa.
Food for thought.
Time
24 hours in 1 day.
60 minutes in 1 hour.
60 seconds in 1 minute.
3600 seconds = 1 hour.
86400 seconds = 1 day.
6 hours is 6/24 of a day.
6/24 is same as 0.25.
0.25 = 1/4.
1/4 = 25%
Do you sleep more than 25% of the day away?
Long Division
Order does not matter.
1 x 0 = 0
1 x 1 = 1
1 x 6 = 6
2 x 3 = 6
Long Multiplication
Order matters here too. Largest number first, for now, to avoid fractions.
There are also a few ways to write this.
12 6 12
÷ 6 ÷ 12 ÷ 2
2 0.5 6
5
3 15
These structures can also be described like this:
15 ÷ 3 = 5
Dividend ÷ Divisor = Quotient
15 / 3 = 5
Dividend / Divisor = Quotient
15 Dividend
÷ 3 Divisor
5 Quotient
5
3 15
