d)2 nhân 4/7=8/7 e) 1 nhân 3/8=3/8 g) 0 nhân 13/18=0
\(0+1+2+3+...+1000\)
\(=\frac{1001\left(1000+0\right)}{2}\)
\(=500500\)
\(0+1+2+3+4+5+...+1000\)
Số số hạng của dãy là : \((1000-0):1+1=1001\)số
Tổng của phép tính là : \(\frac{(1000+0)\cdot1001}{2}=500500\)
Chúc bạn hok tốt :>
\(2+\dfrac{3}{4}=\dfrac{8}{4}+\dfrac{3}{4}=\dfrac{11}{4}\\ \dfrac{5}{7}:6=\dfrac{5}{7}\times\dfrac{1}{6}=\dfrac{5}{42}\\ 2-\dfrac{3}{5}=\dfrac{10}{5}-\dfrac{3}{5}=\dfrac{7}{5}\\ \dfrac{5}{9}\times\dfrac{2}{7}=\dfrac{10}{63}\)
