( 3/4 + 1/2 ) × 5/8 ÷ 2
= 5/4 × 5/8 ÷ 2
= 25/32 ÷ 2 = 25/64
=\(\frac{5}{4}\)+\(\frac{5}{16}\)
=\(\frac{20}{16}\)+\(\frac{5}{16}\)
= \(\frac{25}{16}\)
Chúc e học tốt
\(\left(\frac{3}{4}+\frac{1}{2}\right).\frac{5}{8}:2=\frac{5}{4}.\frac{5}{16}=\frac{25}{64}\)
\(\frac{3}{4}+\frac{1}{2}.\frac{5}{8}:2=\frac{3}{4}+\frac{5}{16}.\frac{1}{2}=\frac{3}{4}+\frac{5}{32}\)
\(=\frac{24}{32}+\frac{5}{32}=\frac{29}{32}\)
Chúc em học tốt!!!
