2) 3/4 * 2/3= 6/12= 1/2

3) 11/18 + 1/2= 11/18 + 9/18= 20/18= 1 2/18= 1 1/9

36. 4 2/3 - 3 5/9 + 7/12 : 3/8= 14/3 - 32/9 + 14/9=  2 2/3

1) 4 2/3 - 3 5/9= 14/3 - 32/9= 42/9 -32/9= 10/9 = 1 1/9

2) 7/12 : 3/8= 7/12 * 8/3 = 14/9 = 1 5/9

2)2 4/9 : 3 2/3= 22/9 : 11/3= 22/9 * 3/11= 2/3

3) 2 2/3 - 2/3= 2

38. 5 1/4* 3 3/7 :( 2 1/4 * 8)= 1

1) 5 1/4* 3 3/7 = 21/4 * 24/7= 18

2) 2 1/4 * 8= 9/4 * 8 = 18

3) 18 : 18= 1
