{1/1000+49/1000} + {13/1000+37/1000}+25/1000=50/1000+50/1000+25/1000
=125/1000
nhớ cho nhé!kb lun
1/1000 + 13/1000 + 25/1000 +37/1000 + 49/1000 = 125/1000
=(1/1000+49/1000)+(13/1000+37/1000)+25/1000
=50/1000+50/1000+25/1000
=100/1000+25/1000
=125/1000
\(\frac{1}{1000}+\frac{13}{1000}+\frac{25}{1000}+\frac{37}{1000}+\frac{49}{1000}\)
\(=\frac{1+13+25+37+49}{1000}\)
\(=\frac{125}{1000}=\frac{1}{8}\)
giải
1/1000+13/1000+25/1000+37/1000+49/1000
=(1/1000+49/1000)+(13/1000+37/1000)+25/1000
=50/1000+50/1000+25/1000
=100/1000+25/1000
=125/1000=1/8
