Question

which properties can be used in computing 2 by 5 into 5 into 7 by 6 + 1 by 3 into 3 into 4 by 11​

Answer 1

Answer

Multiplicative inverse

closure property

Associative property

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]

{multiplicative identify = a*1=a=1=a}

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

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

=7/3+11

{closure property = a+b}

(11*7)+(3*4)/33

after finding LCM

77+12/33

=89/33

=2+22/33[mixed fraction]
