tích đúng cho mình nhé bạn

a)\(\frac{10}{27}\)

b) \(\frac{44}{15}\)

c) \(\frac{100}{147}\)

ccccccccccc

a) 1,2: 3,24 = 120 : 324 = 10:27

b)  = 

c)  = 

a, 1,2 : 3,24 = 120 : 324 = 10 : 27

b, = 11/5 : 3/4 = 44 : 15

c, = 2:2,94 = 200:294 = 100:147

\(a,0,7:1,5=\frac{7}{10}:\frac{15}{10}=\frac{7}{10}\cdot\frac{10}{15}=\frac{7}{15}\)

\(b,2\frac{1}{5}:\frac{3}{4}=\frac{11}{5}:\frac{3}{4}=\frac{11}{5}\cdot\frac{4}{3}=\frac{44}{15}\)

\(c,3:0,02=3:\frac{2}{100}=3\cdot\frac{100}{2}=150\)
