Question

tính nhanh

1/10+20/100+300/1000+4000/10000

Answer 1

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{40000}{100000}\)

\(=\frac{1}{10}+\frac{20}{10}+\frac{30}{10}+\frac{40}{10}\)

\(=\frac{1+2+3+4}{10}\)

\(=\frac{10}{10}\)

\(=1\)

Answer 2

1/10 + 20/100 + 300/1000 + 4000/10000

=1/10 + 2/10 + 3/10 + 4/10

=10/10

=1

Answer 3

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{10000}\)

\(=\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}\)

\(=\frac{1+2+3+4}{10}\)

\(=\frac{10}{10}\)

\(=1\)

tk mk nha

Answer 4

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{100000}\)

\(=\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}\)

\(=\frac{1+2+3+4}{10}=\frac{11}{10}\)

Answer 5

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{10000}\)

\(=\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}\)

\(=\frac{1+2+3+4}{10}\)

\(=\frac{10}{10}=1\)

Answer 6

1/10 + 20/100 +300/1000 +4000/10000

=1/10+2/10+3/10+4/10

=(1+2+3+4)/10=10/10

=1
