6 wholes and 7/12
First we convert them into similar units, giving us 10 fifteenths and 12 fifteenths. Together that is 22 fifteenths or 1 and 7 fifteenths.
It is 1 1/30.
six and a half
5 and 2/3
5 wholes = ten halves plus one half = 11 halves
12 fifteenths (sure?)19 fifteenths = 10 fifteenths (2/3) + 9 fifteenths (3/5)
1/3 + 2/5 = 5/15 + 6/15 = 11/15 (Eleven fifteenths)
When you have 11 halves, you can think of it as having 11 parts, each of which is half of a whole. To find out how many wholes that is, you would divide 11 by 2, since there are 2 halves in a whole. Therefore, 11 halves is equal to 5 wholes with 1 half remaining.
73/4 + 23/4 = 31/4 + 11/4 = 42/4 = 21/2 = 101/2
7 and 8 fifteenths
8/15, 8 fifteenths
6 wholes and 7/12
First we convert them into similar units, giving us 10 fifteenths and 12 fifteenths. Together that is 22 fifteenths or 1 and 7 fifteenths.
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.
It is 1 1/30.
2+6 15ths is 8/15ths, which is just over one 1/2
