Answer:
Step-by-step explanation:
ANS-2 THE PRODUCT OF n NEGATIVE INTEGRES IS NEGATIVE THEN IS ODD AS NEGATIVE MULTIPLIED BY NEGATIVE EVEN NUMBER OF TIMES EVEN = OPTION A
BY EXAMPLE- (-4)X(-6)=24 AND (-4)(-5)(-6)=-120
ANS-3 THE SUCCESOR MEANS PLUS 1 AND PREDECESSOR MEANS -1 i.e (-121)+1=(-120); (-121)-1=-122 =OPTION C
ANS-4 WE SUBTRACT BOTH THE TERMS TO FIND OUT WHAT NUMBER IS BEETWEEN THEM SO (-18)-(-7) = (-11) THEREFORE 11 TERMS OR NUMBERS ARE THERE BETWEEN (-18) AND (-7) = OPTION A
ANS-6 LETS TAKE AN EXAMPLE 24.6/4= 6.105 AND ANOTHER 36.6/6=6.1 BUT 6.6/0=0 WHICH IS A WHOLE NUMBER THEREFORE WHEN A DECIMAL NUMBER IS DEVIDED BY A WHOLE NUMBER OPTION C
ANS-7 6/4= 1.5 , 36/6 = 6 THEREFORE OPTION C
ANS-5 ITS 1/-1=-1 AND 5/-5 = .-1 THEREFORE OPTION B
ANS-8 4 HUNDRETHS OPTION B
ANS-9= 42.8 OPTION A
ANS-10 9.614= OPTION A
