Как сравнить неправильные дроби с разными знаменателями и числителями

Answer 1

Чтобы сравнить дроби с разными числителями, но с одинаковыми знаменателями, больше та дробь, у которой числитель больше.
Чтобы сравнить дроби с разными знаменателями, но с одинаковыми числителями, больше та дробь у которой знаменатель меньше.
Чтобы сравнить две дроби с разным числителем и знаменателем, нужно привести дроби к общему знаменателю и сравнить дроби.

Comparing Improper Fractions with Different Numerators and Denominators

When comparing improper fractions with different numerators and denominators, there are a few steps you can follow to make the comparison easier. Here's a detailed explanation:

1. Convert the improper fractions to mixed numbers (if necessary): If the fractions are already in mixed number form, you can skip this step. Otherwise, convert the improper fractions to mixed numbers by dividing the numerator by the denominator. The quotient becomes the whole number part, and the remainder becomes the numerator of the fraction. For example, if you have the fraction 7/3, you can divide 7 by 3 to get 2 with a remainder of 1. So, 7/3 can be written as the mixed number 2 1/3.

2. Find a common denominator: To compare fractions with different denominators, you need to find a common denominator. The common denominator is the least common multiple (LCM) of the denominators of the fractions. For example, if you have the fractions 2/5 and 3/8, the LCM of 5 and 8 is 40. So, you can convert both fractions to have a denominator of 40.

3. Convert the fractions to have the same denominator: Multiply the numerator and denominator of each fraction by the same value so that they have the common denominator found in the previous step. For example, if you have the fractions 2/5 and 3/8, you can multiply 2/5 by 8/8 to get 16/40, and you can multiply 3/8 by 5/5 to get 15/40.

4. Compare the numerators: Once the fractions have the same denominator, you can compare the numerators to determine which fraction is greater. The fraction with the larger numerator is greater. For example, if you have the fractions 16/40 and 15/40, you can see that 16 is greater than 15. Therefore, 16/40 is greater than 15/40.

It's important to note that these steps assume that the fractions are positive. If you have negative fractions, you may need to consider the signs as well.
