Question

5/7 у + 1/4у +3/14у+1 3/4

Answer 1

Приводим к общему згаменателю 20/28у+7/28у+6/28у+ 1 3/4=33/28у+49/28=1 5/28у+1 3/4

Answer 2

To solve this expression, we can combine the like terms (terms with the same variable and exponent) and simplify the fractions:

5/7у + 1/4у + 3/14у + 1 3/4

To add the fractions, we need to find a common denominator. The smallest common multiple of 7, 4, and 14 is 28. So, we can convert each fraction to an equivalent fraction with a denominator of 28:

(20/28)у + (7/28)у + (6/28)у + 1 3/4

Combining the like terms, we get:

(33/28)у + 1 3/4

To add the mixed number and the fraction, we need to convert the mixed number to an improper fraction. To do that, we multiply the whole number by the denominator and add the numerator. Then, we put the result over the denominator:

1 3/4 = (4 × 1 + 3)/4 = 7/4

So, the expression becomes:

(33/28)у + 7/4

We cannot simplify this any further because the terms have different denominators. So, the final answer is:

(33/28)у + 7/4.
