Explicación paso a paso:
16/100+2/8-1/12
Simplifiquemos
16/100 =4/25
2/8=1/4
Luego
=4/25+1/4+1/12 (común denominador 300)
= 48+75-25 /300 =98/300
=49/150
----------------------------------
25/100 x 5/8 ÷ 15/24
= 1/4 x5/8 ÷ 5/8
=1/4 x 5/8 x 8/5
= 1/4
-------------------------------------
31x5 15/20+9/3 -2/4÷16/40
=31 x5 3/4 +9/3 -1/2 ÷ 2/5
=31 x 23/4 +9/3 -1/2x5/2
=713/4+9/3 -5/4
=708/4 +9/3
=2124+36/12
=2160/12
=180
