Answer 1

Step-by-step explanation:

A) i) 2 3/4 = 11/4

1/2 x 11/4= 11/8

ii)  4 2/9= 38/9

1/2 x 38/9= 19/9

b) i) 3 5/6= 23/6

5/8 x 23/6=115/ 48

ii) 9 2/3 = 29/3

5/8 x 29/3 = 145/ 24

Answer 2

Answer:

a) (1/2) of

1) 2(3/4)

=(1/2)*(2+3/4)

=(1/2)*(11/4)

=11/8

hence 1/2 of 2(3/4) is 11/8

2) 4(2/9)

=(1/2)*(4+2/9)

=(1/2)*(38/9)

=38/18

=19/9

hence 1/2 of 4(2/9) is 19/9

b) 5/8 of

1) 3(5/6)

=(5/8)*(3+5/6)

=(5/8)*(23/6)

=115/48

hence 5/8 of 3(5/6) is 115/48

2) 9(2/3)

=(5/8)*(9+2/3)

=(5/8)(29/3)

=145/24

hence 5/8 of 9(2/3) is 145/24
