The correct answer is (a) 3/4. Converting each fraction to a decimal, we get: 3/4 = 0.75, 5/7 = 0.714, 6/9 = 2/3 ? 0.667, and 7/10 = 0.7. Therefore, 3/4 is the greatest.

The correct answer is d] 5,000%. To convert an integer to a percent, multiply by 100. Therefore, 50 expressed as a percent is 50 × 100 = 5,000%. The other options are incorrect as they do not reflect this conversion.

This problem involves proportional reasoning. We need to set up a proportion: <br>2 apples / P25 = x apples / P100 <br> Cross multiply: 2 * 100 = 25x <br> Solve for x: x = 200/25 = 8 <br>Therefore, 8 apples can be purchased for P100.00.

Hermann Weyl is considered the Father of symmetry in mathematics. Weyl, a German mathematician who lived from 1885 to 1955, made fundamental contributions to many areas of mathematics, including the mathematical foundations of quantum mechanics and general relativity. His book "Symmetry," published in 1952, provided a comprehensive mathematical treatment of symmetry, connecting it to group theory and demonstrating its importance across mathematics, physics, and art. Weyl's work on symmetry has had profound implications in both pure mathematics and theoretical physics.

A chord is a line segment whose endpoints both lie on a circle (or more generally, a curve). It's a fundamental concept in circle geometry. Chords have many important properties and relationships with other parts of a circle, such as radii, tangents, and central angles. Understanding chords is crucial for solving various geometric problems involving circles and is important in fields like engineering and physics.

Irrational numbers are real numbers that cannot be expressed as a simple fraction (ratio of two integers). These numbers have decimal representations that neither terminate nor repeat. Famous examples include ? (pi) and ?2 (square root of 2). Understanding irrational numbers is crucial in advanced mathematics, particularly in algebra and analysis. They play important roles in geometry (e.g., in calculating the diagonal of a square) and in various mathematical proofs and concepts.

A diameter is a line segment that passes through the center of a circle and has its endpoints on the circle. It is the longest chord of the circle and is twice the length of the radius. Understanding the diameter is crucial in geometry for calculating the circumference and area of a circle, as well as in practical applications involving circular objects. The concept of diameter extends to spheres and other geometric shapes in higher dimensions.

The Hindu-Arabic numeral system, which is the most widely used numerical system today, consists of 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This system is also known as the decimal system or base-10 system. Understanding this system is fundamental to arithmetic and forms the basis for our modern number representation. The inclusion of zero as a digit was a significant mathematical innovation, allowing for place value notation and more efficient calculation methods.

The term "floccinaucinihilipilification" is one of the longest words in the English language and refers to the habit of considering something as unimportant or worthless. It originated from a combination of Latin words meaning "at little value."
