Question

: a)24-14\frac{5}{9}=

b)15\frac{7}{18}-11\frac{5}{12}=

c)2\frac{1}{5}+3\frac{2}{9}+4\frac{7}{15}+6\frac{1}{3}=

Answer 1

1) 24-14 5/9= 23 9/9 - 14 5/9 = 9 4/9

 

2) 15 7/18 - 11 5/12 + 15 28/72 - 11 30/72= 14 106/72 - 11 30/72 = 3 76/72 = 4 4/72=4 1/18

 

3) 2 1/5 + 3 2/9 + 4 7/15 + 6 1/3 = 2 18/90 + 3 20/90 + 4 42/90 + 6 30/90 = 15 92/90 + 16 2/90= 16 1/45
