2 The top number of a fraction is the numerator. The bottom number of a fraction is the denominator. 3434 6 th Grade HomePage

3 To change a mixed number into an improper fraction get MAD…Multiply – Add – Put over Denominator 4 ½ 4 x 2 = 8 8 + 1 = 9 9292 To change an improper fraction into a mixed number divide the numerator by the denominator; whatever is left over is the new numerator…keep the same denominator. For Example: 11 4 11 divided 4 equals 2; there is 3 left over. 2 3434 QUIZ 6 th Grade HomePage
