\(=\dfrac{\left(315+372\right)\left(3+7\right)}{2.13.13+74.2.7}\)
\(=\dfrac{687.10}{2\left(169+518\right)}\)
\(=\dfrac{6870}{2.687}=\dfrac{6870}{1374}=5\)
a, [ (315+372) .3 +(372+315).7] /26.13 +74.14
=[ (315+372) .(3+7) ] /26 .13 + 74 .13 +74
= [(315+372).10 ] / (26+74).13 +74
= 687 .10 / 100.13 +74
= 6870 /1374
