A school had 900 students at the start of a school year. If there is
an enrollment increase of 7% by the beginning of the next year, what is the new
enrollment?

• math -

1.07*900

• math -

In other words 100 percent (1.00) plus the new 7 percent (0.07) = 107% or 1.07

• math -

7%100=.7
900/.7=1285.71

• math -

7%/100=0.07
900/0.07=12857.14

• math -

Anonymous,
7%/100 = .07 is correct
however to increase something by 7% you add .07 times the original amount. In other words multiply by 1.07.
What you did was find what 900 was 7% of, a very large number compared to 900.
Use the "does my answer make sense test". If I only increase 900 by 7% will it really be over twelve thousand? That sure would be a lot of new students.
