Is 0.6 less or greater than 0.55

0.6 is greater than 0.55.
The digit closer to the decimal has more value than a digit farther from a decimal.

Let x represent the number of girls.
Then x + 4 represents the number of boys. (there are 4 more boys than girls)
To solve this we can set up a simple equation.

# of girls + # of boys = 16 people
        x      +     (x+4)    = 16
x + x + 4 = 16
2x + 4 = 16
2x = 16 - 4
2x = 12
x = 12 / 2
x = 6

x = # of girls, so there are 6 girls.

Good luck on your math!
