15,2x0,04+15,2x6/100

Answer 1

\(=15,2x0,1=1,52\)

Answer 2

15,2x0,04+15,2x6/100

=15,2x(0,04+0,06)

=15,2x0,1

=1,52

Answer 3

15,2x0,04+15,2x6/100

=15,2x(0,04+0,06)

=15,2x0,1

=1,52

Answer 4

\(15,2\times0,04+15,2\times\dfrac{6}{100}\)

\(=15,2\times\left(0,04+\dfrac{6}{100}\right)\)

\(=15,2\times0,1\)

\(=1,52\)
