\(\frac{3}{5}+\frac{2}{9}+\frac{4}{15}=\frac{27}{45}+\frac{10}{45}+\frac{12}{45}=\frac{27+10+12}{45}=\frac{49}{45}\)
3/5+2/9+4/15=27/45+10/45+12/45=27+10+12/45=49/45
Ủng hộ mình nha !
\(\frac{3}{5}+\frac{2}{9}+\frac{4}{15}=\frac{27}{45}+\frac{10}{45}+\frac{12}{45}=\frac{49}{45}\)
3/5 + 2/9 + 4/15 = 27/45 + 10/45 + 12/ 45 = 27 + 10 + 12 /45 = 49/45
Tik nhaaaa bn yêu
\(\frac{3}{5}+\frac{2}{9}+\frac{4}{15}=\frac{27}{45}+\frac{10}{45}+\frac{12}{45}=\frac{49}{45}\)
là 49/45 nha bạn
olm duyệt nha
mẫu số chung lak 45 đe
đúng lak ok chok
bạn cứ quy đồng mẫu lên rồi tính là được
Ta có:\(\frac{3}{5}=\frac{3x9}{5x9}=\frac{27}{45}\)
\(\frac{2}{9}=\frac{2x5}{9x5}=\frac{10}{45}\)
\(\frac{4}{15}=\frac{4x3}{15x3}=\frac{12}{45}\)
Vậy \(\frac{3}{5}+\frac{2}{9}+\frac{4}{15}=\frac{27}{45}+\frac{10}{45}+\frac{12}{45}=\frac{49}{45}\)
3/5 - 2/9 + 4/15 = 27/45 + 10/45 + 12/45 = 27-10+12/45 = 49/45
\(\frac{3}{5}+\frac{2}{9}+\frac{4}{15}=\frac{27}{45}+\frac{10}{45}+\frac{12}{45}=\frac{27+10+12}{45}=\frac{49}{45}\)
