Answer:

26 girls are there

Step-by-step explanation:

2+1= 3- this is the # of parts the kids are divided into

 

2 - 1 = 1, in one part there are 26 xtra boys

 

26/1=26- there are 26 boys and girls in one part

since there are an extra 26 boys, the boys have an extra part

boys-2 parts   girls-1 part

 

since 1 part has 26 kids , and the boys have 2 parts u need to multiply, 2*26=52, 52 boys in the class

 

since the girls have 1 part and here are 26 kids in one part the # of girls in the class are 26
