Answer: Answer is 40%
Step-by-step explanation: The total number of players in the game is 30 (that is boys and girls added together becomes 18 + 12= 30) altogether which is a hundred percent. The percentage of girls playing the game is calculated as;
12/30 × 100%
=2/5 × 100%
=200/5
=40%
Answer:
4/3
Step-by-step explanation:

Please double-check the original problem. 0.00000.9 is bad form (because of your having two periods in it).
If you wish to divide 0.000027 by <span>0.000009, you could rewrite both numbers in scientific notation and then perform the division:
2.7E(-5) </span>27E(-6)<span>
------------ = ---------------- = 3
9E(-6) 9E(-6)</span>
Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are:
and
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions
and
.
We say they are proportional if
.
Or, if
then we can say the fractions are proportional.
Here the fractions are:
and
.
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
To find this, you have to find the specific cost of each service.
40% fixed costs: 400000 x 0.4 = 160000$
30% fuel: 400000 x 0.3 = 120000$
20% finance: 400000 x 0.2 = 80000$
and 10% maintenance: 400000 x 0.1 = 40000$
So the price was originally $1.50 (for fuel). This means that 120000$ was spent on fuel. Doing the math, it's 120000/1.50 = <span>80000 liters of fuel. So at the new price, the cost of all 80k liters would be 80000 x 1.60 = 128000. That's a 8000 increase in price, so the total cost is now $408000.</span>
