32x50 / 48x75=1600/3600=4/9
63x81 /135x75=5103/10125=63/125
1111x5x1515x7=58 910 775
duyệt mình đi các bạn !
\(\frac{32\cdot50}{48\cdot75}=\frac{1600}{3600}=\frac{4}{9}\)
\(\frac{63\cdot81}{135\cdot84}=\frac{5103}{11340}=\frac{9}{20}\)
1111x5x1515x7=58910775
\(\frac{4}{9}\)
\(\frac{9}{20}\)
\(\frac{11}{21}\)
32x50/48x75=4/9 63x81/135/84=9/20 1111x5x1515x7=58910775
32x50/48x75=4/9
63x81/135x84=9/20
1111x5x1515x7
=58910775
Ta có :\(\frac{32x50}{48x75}=\frac{50:25x32:16}{75:25x48:16}=\frac{2x2}{3x3}=\frac{4}{9}\)
Vậy 32 x 50 / 48 x 75 =4/9
\(\frac{32x50}{48x75}=\frac{2x2}{3x3}=\frac{4}{9}\)
\(\frac{63x81}{135x84}=\frac{7x27}{15x28}=\frac{1x9}{5x4}=\frac{9}{20}\)
1111x5x1515x7=58910775
phép thứ 2 = 5508/11340=17/35
vừa nãy mình tính nhầm nhưng duyệt cho minh nha
