Question

verify associative property under addition by taking a=4/7,b=3/14,c=1/7 please verify this question
​

Answer 1

Step-by-step explanation:

4/7(3/14+1/7)

=4/7.5/14

=10/49

also

4/7.3/14+4/7.1/7

=6/49+4/49

=10/49

so the associative property i,e a(b+c)=a.b+a.c hold

Step-by-step explanation:

$a=\frac{4}{7}$          $b=\frac{3}{14}$           $c=\frac{1}{7}$

$a+(b+c)=(a+b)+c$

$\frac{4}{7}+(\frac{3}{14}+\frac{1}{7})=(\frac{4}{7}+\frac{3}{14})+\frac{1}{7}\\\frac{4}{7}+(\frac{3+2}{4})=(\frac{8+3}{4})+\frac{1}{7}\\\frac{4}{7}+(\frac{5}{14})=(\frac{11}{14})+\frac{1}{7}\\\frac{8+5}{14}=\frac{11+2}{14}\\\frac{13}{14}=\frac{13}{14}\\Verified$
