Let's solve this fraction problem. Two over 8 plus 5 over 8 equals to 2 plus 5 over 8 equals to 7 over 8. Converting to decimal, multiply by 125 over 125, equals to 875 over 1000 equals to 0.875.

Let's understand with an example. Imagine you have a classroom with 30 students. If 12 of them are wearing blue shirts, we can easily calculate that 40% of the students are wearing blue. Simple, right?

Let's explore geometry by starting with triangles. A triangle has three sides and three angles that always sum to 180 degrees. We classify triangles by their angles: acute triangles have all angles less than 90 degrees, while right triangles have one 90-degree angle.

同学们好，今天我们来讲解一个重要的数学概念。解题时要记住，先理解题目要求，再列出已知条件，最后按步骤分析。不要着急，每个步骤都要认真思考。掌握这个方法，难题也能变简单。

Let us understand how to add three-digit numbers with regrouping. Take the example 456 plus 167. First, add the ones: 6 plus 7 equals 13. Write 3 in ones column, carry 1 to tens. Next, add the tens: 5 plus 6 plus 1 carry over equals 12. Write 2, carry 1. Finally, add hundreds: 4 plus 1 plus 1 equals 6.
