Đáp án:
=25/3
Giải thích các bước giải:
`\text{~~Holi~~}`
`C_1: (37/13+25/16):3/5-(9/16-15/13):3/5`
`= (917)/(208).5/3-(-(123)/(208)).5/3`
`= (4585)/(624)+(13)/(208).5/3`
`= (4585)/(624)+(41)/(208).5`
`= (4585)/(624)+(205)/(208)`
`= (25)/3`
`C_2: (37/13+25/16):3/5-(9/16-15/13):3/5`
`= 5/3.((27)/(13)+(25)/(16)-9/16+(15)/(13))`
`= (5)/(3).5`
`= (25)/3`
