The ratio of boys to girls on a swimming team is 3 to 4. the team has 70 members. how many are boys?

Answers

Number of boys are 30

Assume number of boys (X) , Number of Girls (Y)
X + Y = 70 (1)
X/Y = 3/4
Y = 4/3X (2)

replacing the value of Y in (2) in number (1)

X + 4X/3 = 70
7X/3 = 70
7X = 210
X = 30

so number of boys = 30 boys
