Для начала переводишь в обычные дроби без целой части, получается 5 3/4 это 23/4, 2 1/7 это 15/7, 1 1/4 это 5/4, 4 6/7 это 34/7. Далее находим общий знаменатель , в данном случае 28 и считаем. Получается 0.

Answer 2

I can help you with math problems. To solve this problem, we need to follow the order of operations, which is parentheses, exponents, multiplication, division, addition, and subtraction. We also need to convert the mixed fractions to improper fractions. Here are the steps:

- Convert 5 3/4 to 23/4, 1 1/4 to 5/4, and 4 6/7 to 34/7 by multiplying the whole number by the denominator and adding the numerator. - Find the common denominator of 4, 7, and 28 by multiplying them together. The common denominator is 196. - Multiply each fraction by a factor that makes the denominator 196. For example, 23/4 becomes 23/4 x 49/49 = 1127/196. - Perform the addition and subtraction from left to right. For example, 1127/196 - 2 x 196/196 = 1127/196 - 392/196 = 735/196. - Simplify the final fraction by dividing the numerator and denominator by the greatest common factor. For example, 735/196 can be simplified by dividing by 7, which gives 105/28.

The final answer is 105/28 or 3 17/28.
