Question 1163629
There are 152 students in 5th grade.
b + g = 152
 1/11 of the boys and 5 girls join a science club. In the rest of the students, boys and girls are equal.
 b - {{{1/11}}}b = g - 5
{{{10/11}}}b = g - 5
{{{10/11}}}b - g = -5
use elimination
{{{10/11}}}b - g = -5
 b + g = 152
--------------------Adding eliminates g, find b
{{{21/11}}}b = 147
21b = 147*11
21b = 1617
b = 1617/21
b = 77 boys
then
152-77 = 75 girls


How many boys vs girls are in 5th grad.
