Question

check the commutative property for addition and multiplication of the rational numbers -10/11,5/6,-4/3​

Answer 1

Answer:

Commutative property if addition and multiplication of given rational are true

Step-by-step explanation:

1) addition:

Communtative property of addition

a+b+c=c+b+a

a+b+c=(-10/11) +(5/6) +(-4/3) lcm=66, on solving we get a+b+c=(-31) /22

c+b+a=(-4/3) +(5/6) +(-10/11) lcn=66

On solving c+b+a=(-31) /22

So both are equal. Hence commutative property of addition is proved

2) Communtative property of multiplication

(a/b) *(c/d) *(e/f) =(a*c*e) /(b*d*f)

(a/b) *(c/d) *(e/f)=(-10/11) *(5/6) *(-4/3) =100/99

(a*c*e) /(b*d*f) =((-10) *5*(-4)) /(11*6*3) =100/99

So both are equal. Hence commutative property of multiplication is proved
