Answer 1

1. B
2.C
3.A
4.C or B
I`m really not sure of the answer for number for but I`m really thinking its C but i highly recommend you to ask someone else! 

Answer 2

1) 60 + 90 = 150 so it's (B)
2) -36/3= -12 so it's (A)
3) 19 x 10= 190 so it's (A)
4) In this one you have to make an educated guess. Between 1+ 1.8= 2.8 and 2+ 1.8= 3.8, which one is closest to 3.14? The answer would be (B)
