3.5
Google has a calculator built in - Just search 1.75+1.75
To calculate in your head I would do it like this
1+1 = 2
0.75 +0.75 = 1 +0.5
1+0.5 = 1.5
2+1.5 = 3.5
4 + 6 + 12 + 175 = 197
200 + 175 + 286 + 304 + 321 = 1,286
175 + 35 = 210
140 + 175 = 315
175 + 20% = 210
175 + 185 = 360:D
175 + 673 = 848
77 + 98 = 175

175 + 1985 + 350 + 55 + 950 + 300 + 500 + 125 + 700 = 5140
Arithmetic fact: 7 x 25 = 175 35 + 140 = 175 175 = 175
