Answer 2

Answer:

Associative property, Commutative property and Closure property can be used in computing this equation.

2/5*(5*7/6)+1/3*(3*4/11)

= (2/5*5)*7/6+(1/3*3)*4/11

[Associative property . a*(b*c)=(a*b)*c]

=[(2*1)*7/6]+[(1*1)*4/11]

[Commutative property. a*1=a=1*a]

=(2*7/6)+(1*4/11)

=(1*7/3)+(1*4/11)

=7/3+4/11

[Closure property . a+b]

=(11*7)+(3*4)/33 {after finding LCM}

=77+12/33

=89/33

=2+22/33 {mixed fraction}
