Answer:
2, 3, 5, 7 and 11 are the first few prime numbers.
Step-by-step explanation:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.
Triangle ABC is similar to triangle CEF.
<u>Explanation:</u>
<u></u>
Diagram is inserted for the reference.
ABCD is a rectangle.
ABC is a right angled triangle because all the angles of the rectangle are 90◦ - (a)
CEF is a right angled triangle because FE is perpendicular to DC – (b)
In triangles ABC and CEF,
1. Angle ABC = Angle CEF = 90◦ (Both are right angles from a and b)
2. Angle BCA = Angle EFC (Alternate angles on parallel lines are equal on intersection)
Hence using Similarity property of AA (Angle, Angle), Triangle ABC and CEF are similar.

If written as a decimal, 9 x 1/10 would be 9 x 0.1,
6 x 1/100 would be 6 x 0.01, and 4 x 1/1000 would be 4 x 0.001.
