Hola! :3
Resolvemos:
1) El 10% de 120:
(10%)(120)=a
(10/100)(120)=a
(1/10)(120)=a
120/10=a
12=a
2) El 30% de 80:
(30%)(80)=b
(3/10)(80)=b
(80/10)(3)=b
8(3)=b
24=b
3) El 45% de 180:
(45%)(180)=c
(45/100)(180)=c
(9/20)(180)=c
(180/20)(9)=c
9(9)=c
81=c
4) El 5% de 150:
(5%)(150)=d
(5/100)(150)=d
(1/20)(150)=d
150/20=d
15/2=d
7.5=d
Espero haberte ayudado :D
