What is 4.5 as a improper fraction?
To convert a decimal to an improper fraction, you first write the decimal as a fraction with the decimal as the numerator and a power of 10 as the denominator. In this case, 4.5 can be written as 4.5/1. To convert this to an improper fraction, you multiply both the numerator and denominator by 10 to get 45/10. Simplifying this fraction by dividing both the numerator and denominator by 5 gives us the improper fraction 9/2.
How do you make a proper fraction into an improper fraction?
Ussaly when you have an improper fraction, you need to convert it into a mixed number, which means dividing out the parts that give you a whole number and leaving the extras in the fraction An exmple is 9/5, first you take out 5 from the top, to get a one, and are left with 4/5, so your answer is 1 4/5.
When the numerator is bigger than the denominator a fraction is?
There is no specific name. -3 is greater than -4 and (-3)/(-4) = 3/4 is a positive proper fraction. 3 is greater than -4 and 3/(-4) = -3/4 is a negative proper fraction. 3 is greater than -2 and 3/(-2) = -3/2 is a negative improper fraction. 4 is greater than 3 and 4/3 is a positive improper fraction. Thus, the fraction can be negative or positive, proper or improper.
How do you multiply a fraction and a whole number with a fraction?
Best shown with an example. Say 2/3 X 5 4/5 #1 convert to an Improper (top heavy) fraction Hence 2/3 X 29/5 #2 cancel down where possible. In this case cannot cancel down; no common factors. #3 ; multiply the numerators(top) together, and then multiply the denominators(botton). Hence 58/15 #4 ; Convert back to a mixed number. 58/15 = 3 13/15 The answer!!!!
How do you write an improper fraction as a whole or mixed number?
Mixed numbers include both integers and fractions. Example : 1 1/2Improper fractions have a larger numerator than denominator (they have a value greater than 1).Example : 14/7These forms are interchangeable. Multiplying the whole number by the denominator, and adding, will change a mixed number to an improper fraction.2 3/4 = [(2x4) + 3] / 4 = 11/4To change an improper fraction to a mixed number, divide the numerator by the denominator, and combine the whole number with the remaining fraction.15/7 = 2 plus remainder 1 = 2 1/7
