Reset Additional Quiz Represent as Simplest Fraction Handout for Grade 8-10 Students Key Points Converting decimals to simplest fractions involves turning terminating decimals (e.g., 0.75) and repeating decimals (e.g., 0.666...) into fractions and simplifying them. Terminating decimals are converted by writing them as fractions with denominators as powers of 10, then simplifying. Repeating decimals use an algebraic method to eliminate the repeating part. Simplifying fractions requires finding the greatest common divisor (GCD) to reduce the fraction to its simplest form. Converting Terminating Decimals Terminating decimals, like 0.75, end after a finite number of dig...

Quiz 1:   Fullscreen Mode 🧪 METALS & REACTIVITY SERIES: Complete Theory & Formulas 🔬 I. FUNDAMENTAL THEORIES OF METALS 1.1 Electronic Theory of Metallic Bonding Sea of Electrons Model: Metals consist of a lattice of positive metal ions surrounded by a "sea" of delocalized electrons. This explains conductivity, malleability, and ductility. Metal Atom → Metal Ion⁺ + e⁻ M(s) → M⁺(aq) + e⁻ (general form) 1.2 Density Theory & Formula Density is a fundamental physical property that measures mass per unit volume. Density = Mass ÷ Volume ρ = m/V (g/cm³ or kg/m³) High Density Examples Gold: 19.3 g/cm³ Lead: 11.4 g/cm³ Copper: 8.9 g/cm³ ...

Sifat Utama Magnet Menarik bahan magnetik (besi, baja, nikel, kobalt). Mempunyai dua kutub: Kutub Utara (N) dan Kutub Selatan (S) . Kekuatan terbesar ada di kutub-kutubnya. Jika digantung bebas, selalu sejajar utara–selatan bumi . Like poles repel (N–N atau S–S tolak-menolak) dan unlike poles attract (N–S tarik-menarik). Bahan Magnetik vs Non-magnetik Bahan Magnetik Bahan Non-magnetik Besi, Baja, Nikel, Kobalt Aluminium, Tembaga, Plastik, Kayu Induksi Magnet Bahan magnetik dapat menjadi magnet sementara ketika berada di dekat magnet. Proses ini disebut induksi ; kutub yang terbentuk selalu berlawanan dengan kutub mag...
