8.66-3.86=4.8=4 wholes and 17 over 21
1 1/3
38 over 21 or thirty-eight twenty-firsts
6 Thirds are in 2 wholes. 3 in 1 whole.
31/3 − 2/3 = 8/3 or 22/3
negative 2 sevenths(-2/7)
6 and 2 sevenths
5 wholes is 15 thirds so your improper fraction is 17/3
(6 × 7) ÷ 2 = 21
10 and 6 sevenths
Yes, that's quite correct.Two thirds is four thirds less than two wholes,and two thirds is one sixth more than a half.
No
1 whole = 4 fourths 4 wholes = 16 fourths 4 wholes minus 2 fourths = 16 fourths minus 2 fourths = (16 - 2) fourths = 14 fourths 14 fourths = 3 wholes plus 2 fourths, or 3 wholes plus 1 tooth.
