Associative Property
Multiplicative Inverse
Closure Property
Step-by-step explanation:
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]
=(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}
HOPE THIS HELPS YOU!
