1. When calculating the product of two fractions, the following formula can be used: (a1/b1) × (a2/b2) = (a1a2)/(b1b2).
The meaning of this formula is to find the numerator a 1 and a2 of two fractions, and then find the denominator b 1 and b2 of two fractions. Just multiply the molecule a 1 by a2 and the denominator b 1 by b2. In this way, the answer of the product of two fractions is obtained.
2. Fraction consists of numerator and denominator, and is expressed by a/b, where A is numerator and B is denominator. For example, 2/3 is a fraction, which means 2 divided by 3. For example, calculate (2/3)×(3/4).
The numerator is 2 and 3, and the denominator is 3 and 4. Multiply 2 by 3 to get 6. Multiply the denominator 3 by 4 to get 12. (2/3)×(3/4)=6/ 12。 So you can multiply the scores. This method can not only get the answer quickly, but also better understand the principle of fractional multiplication.
The focus of sixth grade study:
1, lay a good foundation of knowledge: the sixth grade is an important period of knowledge accumulation, and students need to master the basic knowledge and skills of various subjects. This includes the basic concepts, principles and problem-solving methods of Chinese, mathematics, English, science, history and geography. Only by mastering these basic knowledge can we better cope with the learning challenges of junior high school.
2. Cultivate good study habits: The sixth grade should not only pay attention to knowledge learning, but also cultivate good study habits. This includes making study plans, reviewing regularly, thinking independently and finishing homework carefully. Good study habits not only help to improve study efficiency, but also lay a solid foundation for future study.
3. Develop comprehensive quality: In addition to subject knowledge and study habits, sixth-grade students need to pay attention to developing comprehensive quality. This includes teamwork, leadership, innovation and critical thinking. These qualities are very important in future study and career, so they need to be cultivated in primary school.
