Answer 2

Answer:

Explanation:

2. 6/21=*0.28571

option a: -20/70=-0.28571

option b: -10/35=-0.28571

option c: -13/2=-6.5

so option c is not equivalent to given fraction

or we can also do like this take from option each option check

-6/21=-2/7

option a:-(2/7),(-2/7)

option b:(-2/7),(-10/35)=-2*35,-10*7=-70,-70

cross multiply the denominator with numerator and numerator of the second fraction with denominator of first fraction.

3. cube of  a negative integer is always negative

4. 12/(-3)=-12/3=-4

5. absolute value of -3/11=3/11

6. px(-9)=135

p=135/(-9)

=-135/9=-15

7. a. (-59)*(-19)+59=1121+59=1180

b. (-1)*(-2)*(-3)*(-4)*(-5)=-120
