Answer:1 computer : 8 students
Step-by-step explanation:
if there are 9 computers it would originally be 9 : 72 but that can be reduced since 9 is a factor of 72.
2/5 multiply the top and bottom number by 20 you get 40/100 which is the same as 40%
What is the question you are asking and no one is gonna know what lesson 3.2 means.
We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
