Question

Решить дроби 5 7/8+6 3/10​

Answer 1

Ответ:

Пошаговое объяснение:

5 7/8 + 6 3/10 = 5 35/40 + 6 12/40 = 11 47/40 = 12 7/40

Answer 2

Ответ:

5 7/8+6 3/10=(5+6)+(7/8+3/10)=11+(35+12/40)=11 47/40 =12 7/40

Пошаговое объяснение:

7/8+3/10 нужен общий знаменатель будет 40 если 40:8=5 40:10=4 потом 7 нужно умножить на 5, а 3 на 4

11 47/40 из этого выделаем целую часть и это будет 12 7/40

Answer 3

To solve the addition of mixed fractions, you need to convert them into improper fractions, find a common denominator, add the fractions, and simplify if necessary. Let's solve the expression:

First, convert the mixed fractions into improper fractions:

5 7/8 = (5 * 8 + 7) / 8 = 47/8 6 3/10 = (6 * 10 + 3) / 10 = 63/10

Now, find a common denominator. In this case, the common denominator is 8 * 10 = 80.

Convert both fractions to have a denominator of 80:

47/8 * 10/10 = 470/80 63/10 * 8/8 = 504/80

Now, add the fractions:

470/80 + 504/80 = (470 + 504) / 80 = 974/80

The result is the fraction 974/80. It can be simplified by finding the greatest common divisor (GCD) of the numerator and denominator, which is 2:

974/80 = (2 * 487) / (2 * 40) = 487/40

So, the final result is 487/40.
