a, 0,125 x 6,135 x 24 = \(\left(0,125\times4\right)\times6,125\\ =0,5\times6,125=3,0625\)
b, 5m2 7dm2 + 2,6 m2 + 3,33 m2 = 5,07m2+2,6m2+3,33m2
\(=\left(5,07+3,33\right)+2,6=8,4+2,6=11\)
a, 0,125 x 6,135 x 24
(0,125 x 24) x 6,135
=3x 6,135
= 18,405
b, 5m2 7dm2 + 2,6 m2 + 3,33 m2
= 5,07m2 + 2,6m2 + 3,33m2
= ( 5,07m2 + 3,33m2 ) + 2,6m2
= 8,4m2 + 2,6m2
= 11m2.
