4) value of 0÷ (-4/7) is 0.
Because 0÷ a for any number is always 0.
5)x = 7/15 and y = -2/21
So, x-y = 7/16 - (-2/21)
= 7/15 + 2/21
= (49+10)/105
= 59/105

Hey friend,
(4)The value of 0÷(-4/7)
0÷(-4/7)
=0×7/-4
=0/4
=0
→0 divided by any number is always 0.
0/a=0
(5)The value of (x-y) where x=7/15 and y=-2/21
(x-y)=(7/15)-(-2/21)
=7/15+2/21
Take LCM,
LCM is 105,
=7/15×7/7 + 2/21×5/5
=49/105+10/105
=(49+10)/105
=59/105
Hope it helps
