Đáp án:
`5/16 . 24/15 + 2/4 . 4/3 – 7/6`
`= 1/2 + 2/3 – 7/6`
`= 3/6 + 4/6 – 7/6`
`= 0`
`25% – 4/12 + 5/9 – 16/18`
`= 1/4 – 1/3 + 5/9 – 8/9`
`= 1/4 – 1/3 -1/3`
`= 1/4 – 2/3`
`= 3/12 – 8/12`
`= -5/12`
`12/15 – |- 4/24| + 8/60 – (-2020/2021)^0`
`= 12/15 – 4/24 + 8/60 – 1`
`= 4/5 – 1/6 + 2/15 – 1`
`= 24/30 – 5/30 + 4/15 – 30/30`
`= -7/30`
