Simple calculation of 5 / 7 + (5 / 6 + 2 / 7)

5 out of 7 + (5 out of 6 + 2 out of 7)
=5/7+2/7+5/6
=1+5/6
=1 and 5 / 6
[I hope I can help you]

3.63-1.25 + 17.37-8.75 19.53 × 101-19.53
3.63-1.25 + 17.37-8.75 19.53 × 101-19.53 75.68 - (5.67 + 27.36)

＝（3.63+17.37）-（1.25+8.75）
＝ 21-10
＝ 11

Simple calculation of 8 1 / 4-2 3 / 5 + 1.75-2 2 / 5

8 1 / 4-2 3 / 5 + 1.75-2 2 / 5
=(8 1 / 4 + 1.75) - (2 3 / 5 + 2 2 / 5)
=(8 1 / 4 + 1 3 / 4) - 5
=10-5
=5

1 by 3:1 + 3 by 5:1 + 5 by 7:1 + 7 by 9:1 + 9 by 11:1 + 11 by 13:1
1 by 3:1 + 3 by 5:1 + 5 by 7:1 + 7 by 9:1 + 9 by 11:1 + 11 by 13:1

The score is not good. I'll make do with it
1/3+3/5+5/7+7/9+9/11+11/13
= (1-2/3)+(1-2/5)+(1-2/7)+(1-2/9)+(1-2/11)+(1-2/13)
=6-(2/3+2/5+2/7+2/9+2/11+2/13)
=6-2*(1/3+1/5+1/7+1/9+1/11+1/13)
It's a little easier to share in this way
I haven't thought of a simpler way to change it
Original formula = 6-2 * (43024 / 45045)
=4+4042/45045
