3/10, 30%, 0.3
because 3/10 basically means 3 out of 10. that's 30%. 0.3 is just 3/10 in decimal form.
6.5+7+7.5+8+8+8+9+10+10.5
= 13.5 + 7.5 +8+8+8+9+10+10.5
= 21+8+8+8+9+10+10.5
= 29+8+8+9+10+10.5
= 37+8+9+10+10.5
= 45 + 9 + 10 + 10.5
= 54 + 10+10.5
= 64+10.5
= 74.5
I hope that's help !

Answer:
Step-by-step explanation:
x=# of boys, y=# of girls
after 24 boys have left, we have 3 times as many girls
y=3(x-24)
because there are the same number of girls as boys - we create this equation
x=y
then we can use substitution
y=3(y-24)
y=3y-72
-2y=-72
y=36
because there are 36 boys, that means there are also 36 girls - leaving you with 72 children in the beginning.
hope this helps!!
