What is the number?</h3>
Percentage can be described as the fraction of an amount that is expressed as a number out of hundred. The sign used to represent percentage is %. Percentages are a measure of frequency.
When the number is decreased, the number becomes smaller. This means that the original number is larger than 81.
The equation that can be used to represent the information in the question is:
(1 - percentage decrease) initial number = 81
(1 - 0.1)x = 81
0.9x = 81
x = 81 / 0.9
x = 90

In the parallelogram ABCD, join BD.
Consider the triangle Δ ABD.
It is given that AB > AD.
Since, in a triangle, angle opposite to longer side is larger, we have,
∠ ADB > ∠ ABD. --- (1)
Also, AB || DC and BD is a transversal.
Therefore,
∠ ABD = ∠ BDC
Substitute in (1), we get,
∠ ADB > ∠ BDC.

Answer:
0.27
Step-by-step explanation:
Since it's given that the student is dropped off by parents, we can ignore all the students who take the bus, so our total population is 0.45. So now we just take the seventh grade students, 0.12, and divide by the total students whose parents drop them off, 0.45.
0.12/0.45 = 0.266666, round up to 0.27.
