Sarina is mixing paint. If she adds 1/4 gallon blue, 1/4 gallon red, and 1/4 gallon white, how much total paint does she have?

If Sarina adds 1/4 gallon blue, 1/4 gallon red, and 1/4 gallon white paint, she will have 1/4 + 1/4 + 1/4 = <<1/4+1/4+1/4=3/4>>3/4 gallon total paint. Answer: \boxed{\frac34}.
