Elementary Mathematical Olympiad: How to Turn Recurring Decimals into Fraction

Mixed repeating decimals referred to decimals with a repeating structure. For example, 1/314159 could be written as 1/3(where 3 is a loop) or 1/314159(where 14159 is a loop). If you wanted to convert the mixed loop decimals into a fraction, you needed to find the loop section where the decimal loop part was located and then divide the loop section into several parts and express it as a fraction. For example, 1/314159 could be written as a fraction: 1/3 = 3/3 = 1 1/314159 = 3/314159 = 114159 Here, the fraction 3 and the 14159 were divided into three parts, which were represented by the fraction 1 and 114159 respectively. Continuing example: 1/520303 can be written as a fraction: 1/5 = 2/5 = 040203 1/520303 = 2/520303 = 040203 Here, the fraction 5 and the 20303 were divided into five parts, which were represented by the scores 040203 and 20303 respectively. By analogy, one could find the loop section where the loop part was located and then divide it into several parts and express it with scores.

The choice of Mathematical Olympiad books depended on one's interests and level of mathematics. For the fifth grade students, it is recommended to choose a book suitable for the basic level and pay attention to interest and inspiration. Some examples of Mathematical Olympiad books suitable for fifth grade elementary school students include: - Elementary Mathematical Olympiad ( ) - "Primary School Mathematical Olympiad Real Reality Simulation Test Questions"( ) - Math Paradise ( ) These books cover basic mathematics knowledge and provide a variety of topics and challenges suitable for stimulating students 'interest in learning and improving their mathematical ability. Of course, he could also choose some more advanced course books to challenge his own mathematics level. It is recommended that you carefully evaluate your mathematics level and interest before buying.

He looked at the camera. One of the screens displayed Peng Kun's current information. [System: Peng Kun] Position: Director of the Universe Research Institute [Laboratory Area: 30 hectares] [Main structure of the research center: office building, warehouse, factory, vegetables] [Staff: 0] [Question: Unknown] [Current amount: 0] [Value: 0] [The system will build a world-class, multi-purpose research institute for you. You will receive a handsome reward.]

It can be very relevant. A mathematical comic can make complex concepts more accessible and fun, increasing understanding.

Fraction stories can make the concept more relatable. For example, if you tell a story about sharing a cake among friends. Say there are 4 friends and a cake is divided into 8 slices. Each friend gets 2 slices, which is 2/8 or 1/4 of the cake. Kids can better understand the idea of fractions as parts of a whole through such stories.

Well, when writing decimals in fiction, make sure they're clear and not confusing for the readers. Use them sparingly and only when necessary to add precision to your story.

To write a fraction story, first, decide on a simple fraction. Then, create characters or situations that help explain it. For instance, if it's 1/2, you could have two friends sharing a pizza evenly. Add some twists and turns to make it interesting.
