Question

(i) find the product of 3/8 and the reciprocal of -1 whole 5/19

(ii) represent on number line (i) 9/11

(ii) 5/9

(iii) -4/15

(iii) if a=1/2 and b=3/4 and c=5/8

then verify (i) (a+b)+c= a+(b+c)

(ii) (a*b)*c= a*(b*c)

(iv) by using properties calculate(i) -4/5*3/7+4/5*3/7

(ii) {-8/9*1/-5}+{-8/9*-7/11}

Answer 1

1. Answer:

3)

1.

= (1/2+3/4)+5/8=1/2+(3/4+5/8)

= (2+3/4)+5/8=1/2 + (6+5/8)

= 5/4+5/8=1/2+11/8

=10+5/8=4+11/8

=15/8=15/8

2.

=1/2*3/4*5/8=1/2*3/4*5/4

=15/69=15/69
