Arithmetic method: solution: 52-5= 147 (person)

If five girls are reduced from the total number of students, while the boys remain the same.

Then there are fewer girls than boys111.

That is, the number of girls is1011.

A * * * There are boys:147 ÷ (1+(10/1)) = 77 (people).

I have a girl: 152-77=75 (person)

A: Omit.

Solution 2: Equation Method:

Solution: Suppose there are X boys in the fifth grade, then there are 152-x girls.

x- 1/ 1 1x = 152-x-5

10/ 1 1x = 147-x

10/ 1 1x+x = 147

2 1/ 1 1x = 147

x=77

152-77=75 (person)

A: A little.
