Метод дробей: дроби, десятичные и проценты для взрослых — 9 прогрессивных серий с 135 упражнениями и полными решениями

You are an adult and fractions always left a sour taste from school. You calculate a discount and second-guess yourself. Someone mentions tax, ratios, or interest -- and out comes the calculator, without really understanding what it is doing. This workbook is built for you. No abstract theory, no jargon -- just a clear, step-by-step method to finally master fractions, decimals, and percentages. Across 9 progressive series, you start from the basics (what a fraction actually is, how to simplify it) and work all the way up to real-life applications (store discounts, price increases, recipe ratios, rule of three). Each series gives you 15 carefully chosen exercises with detailed solutions that explain the method, not just the final answer. Whether you are preparing for an exam, helping a child, trying to manage your budget better, or simply filling a gap you have carried for years, this workbook is your starting point. Fifteen minutes a day for a few weeks -- and fractions, decimals, and percentages finally feel natural.
