so sánh: 459 và 380
so sánh: -371/ 459 và -371/ -459
so sánh -371/159 và -371/-459
Ta có: \(\dfrac{-371}{-459}=\dfrac{371}{459}\) là một số dương
=> \(\dfrac{-371}{-459}>\dfrac{-371}{159}\)
so sánh -315/380 và -316/381 (làm cách nhanh nhất)
`@` `\text {Ans}`
`\downarrow`
`315/380 = 1 - 65/380`
`316/380 = 1 - 65/381`
Mà `65/380 > 65/381`
`-> 1 - 65/380 < 1 - 65/381`
`-> 315/380 < 316/381`
`=> -315/380 > -316/381`
315/380=1-65/380
316/381=1-65/381
mà 65/380>65/381
nên 315/380<316/381
=>-315/380>-316/381
so sánh \(\dfrac{-315}{380}\) và \(\dfrac{-316}{381}\)
Giúp mình với ạ, đúng sẽ tick nha
-315/380 = -120015/144780
-316/381 = -120080/144780
Do -120015 > -120080
-120015/144780 > -120080/144780
⇒ -315/380 > -316/381
