you are looking at the hundreds place to decided if one runs up or not. 5 or higher rounds up, 4 to zero stays the same

#2: 2913 = 3000; 9912 = 10000
10000 + 3000 = 13000
B.13000

#3: 27 x 4 = 108
if 'friendly' means making it easier, like 27 becomes 30 and 4 becomes 5, well idk what friendlier means so... i give you the exact number. But it looks like 30 x 5 if that is what friendlier means

#4: 78 + 45 = 80 + 50 (round it up)
80 + 50 = 130
D) 130

#5  4.8 x 9.2 = 44.16

closest is 45.36 so...
B) 45.36


hope this helps
