I'm 95% sure that these are the answers:
11.- Oscuridad. 16.-Por favor
12.-Voz. 17.-Nada
13.-Me. 18.- Tengo
14.-hijo 19.-Ya
15.-Espérame, estoy aquí. 20.-Lo ruego.
It depends on where you live like mines Tampa FL cause I live in Florida theres others in FL but thats the one I used when I went on a cruise.
5 to 2 = 10 to 4(5x2=10 2x2=4)
14/21=10/15
14/21=0.6666666666
10/15=0.6666666666
Equivalent
3/5=0.6 21/35=0.6
I think the answer is “te las”
