tính

0,5. 4/3.25% : 2/5 + 3/5

Answer 1

\(0,5.\frac{4}{3}.25\%:\frac{2}{5}+\frac{3}{5}\)

\(=\frac{1}{2}.\frac{4}{3}.\frac{1}{4}.\frac{5}{2}+\frac{3}{5}\)

\(=\frac{5}{12}+\frac{3}{5}\)

\(=\frac{25}{60}+\frac{36}{60}\)

\(=\frac{71}{60}\)

Answer 2

    0,5.4/3.25%:2/5+3/5

=  1/2.4/3.1/4:2/5+3/5

=  2/3.1/4.5/2+3/5

=  1/6.5/2+3/5

=   5/12+3/5

=   25/60+36/60

=   61/60
