5 / 7 * 9 / 8 + 7 / 8 * 5 / 7-5 / 7 (simple calculation)

5 / 7 * 9 / 8 + 7 / 8 * 5 / 7-5 / 7 (simple calculation)

5/7*9/8+7/8*5/7-5/7
=5/7*（9/8+7/8-1）
=5/7*1
=5/7

Simple calculation: 52 * 11 and 1 / 10 + 2 and 3 / 5 * 778

52 * 11 and 1 / 10 + 2 and 3 / 5 * 778
=52*11.1+2.6*778
=26*2*11.1+26*77.8
=26*（22.2+77.8）
=26*100
=2600

(3 / 29 + 1 / 13) * 13 * 29 calculation, can be simple to calculate

（3/29+1/13）*13*29
=3/29x13x29+1/13x13x29
=39+29
=68

29 out of 23 - (3 out of 13 + 5 out of 7) I'm online for an hour

29 of 23 - (3 of 13 + 5 of 7)
=29 of 23-86 of 91
=661 out of 2093
It can't be simplified
thank you
