To provide info
Step-by-step explanation:
There were 18 girls because 27 divided by 3 is 9 so then you do 2 times 9 which is 18 :)
add 0+1+2+3+4 = 10
divide 10÷5 = 2
add 15+8+3+3+1 = 30
divide 30÷5 = 6
the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.
Subtracting Integers
Subtract +9 - +4 =
Add The Opposite +9 + -4 =
Result +5
90/135 = 0.666666667
0.666 x 100 = 66.6 %
