Mixed Numbers are composed of a whole number and a fraction. 4½ is a mixed number while 6/4 is an improper fraction. 6/4 is equivalent to 1½. The way to simplify a mixed number is to first divide the denominator into the numerator. (6÷4 is 1.5) Then keep the whole number and put the numbers after the decimal over the number according to the decimal. (.5 is in the tenths place so put five over ten[5/10] and simplify to ½.)The most important rule with fractions and whole numbers is to simplify!
+3 ¼ = 3 7/28
- 6 5/8= 6 5/8
3. Subtract. 2 6/8= 2 3/4
Multiplying is pretty easy.
4/5 x 7/8= 1/5 x 7/2= 7/10
Dividing is just like multiplying.
4 ¾ 4÷3=.75 4.75
½ 2÷1=.5 0.5
24 ¼ 4÷1=.25 24.25
77%= .77 64%= .64 2%= .02 724%= 7.24
