2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
KengaRu [80]

Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = \frac{2}{9}x

Number of girls = \frac{2}{9}x +95

Number of boys + Number of girls = total members

\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9

x = 171

Number of boys = \frac{2}{9}*171 = 2 * 19 = 38

Number of girls = 38 + 95   = 133
