Question

Tính nhanh:

\(\frac{4,5x19,375x0,4}{3,125x1,2x1,5x6,2}\)

HELP ME PLEASE!!!!

Answer 1

\(\frac{4,5\cdot19,375\cdot0,4}{3,125\cdot1,2\cdot1,5\cdot6,2}\)

\(=\frac{4,5\cdot0,4\cdot19,375}{3,125\cdot6,2\cdot1,2\cdot1,5}=\frac{1,8\cdot19,375}{19.375\cdot1,8}\)

\(=\frac{34,875}{34,875}=1\)

Answer 2

=\(\frac{1,2x3,75x3,125x6,2x0,4}{3,125x1,2x1,5x6,2}\)=\(\frac{3,75x0,4}{1,5}\)=\(\frac{1,5x2,5x0,4}{1,5}\)=\(2,5x0,4\)=\(1\)
