Question

Решить (2/35+ 3/28)+1/28

Answer 1

(2/35+ 3/28)+1/28 = 2/35 + 3/28 + 1/28 = 2/35 + 4/28 = 2/35 + 1/7 = 2/35 + 5/35 = 7/35 = 1/5

Answer 2

To solve the expression (2/35 + 3/28) + 1/28, follow these steps:

Step 1: Find a common denominator for the fractions. The least common multiple (LCM) of 35 and 28 is 140. So, we'll rewrite the fractions with a denominator of 140:

(2/35) = (2/35) * (4/4) = 8/140 (3/28) = (3/28) * (5/5) = 15/140 (1/28) = (1/28) * (5/5) = 5/140

Step 2: Add the fractions together. (8/140) + (15/140) + (5/140) = (8 + 15 + 5) / 140 = 28 / 140

Step 3: Simplify the fraction (if possible). The numerator and denominator have a common factor of 28, so we can simplify the fraction:

28 / 140 = (28/28) * (1/5) = 1 * (1/5) = 1/5

The simplified result of the expression is 1/5.
