(2)/(7)quad (ii)(5)/(-3)

Give four rational numbers equivalent to: (i) (-2)/(7)( ii) (5)/(-3)( iii) (4)/(9)

Calculate each of the following using multiplication. (i) (3)/(7) of (2)/(5) (ii) (3)/(5) of (2)/(7) (iii) (2)/(3) of (3)/(4) iv) (5)/(6) of (3)/(10) .

Multiply: (7)/(11)by(5)/(4) (ii) (5)/(7)by(-3)/(4)

Verify the following: (i) (-12)/(5)+(2)/(7)=(2)/(7)+(-12)/(5) (ii) (-5)/(8)+(-9)/(13)= (-9)/(13)+(-5)/(8) (iii) 3+(-7)/(12)=(-7)/(12)+3 (iv) (2)/(-7)+(12)/(-35)=(12)/(-35)+(2)/(-7)

Give four rational numbers equivalent to: (i) (-2)/7 (ii) 5/(-3) (iii) 4/9

Simplify: (-3)/(2)+(5)/(4)+(7)/(4)( ii) (5)/(3)-(7)/(6)+(-2)/(3)
