Question

a 151/ 453 x X =44/ 99 b 102/ 408 xX= 2242 /3363

giúp mình với

 

Answer 1

\(a,\frac{151}{453}\times x=\frac{44}{99}\)

\(\frac{1}{3}\times x=\frac{4}{9}\)

\(x=\frac{4}{9}\div\frac{1}{3}\)

\(x=\frac{4}{3}\)

Answer 2

\(b,\frac{102}{408}\times x=\frac{2242}{3363}\)

\(\frac{1}{4}\times x=\frac{2}{3}\)

\(x=\frac{2}{3}\div\frac{1}{4}\)

\(x=\frac{8}{3}\)
