Question

Икс минус три седьмых равно две целых восемь десятых

Answer 1

Х-3/7=2,8
х=2,8+3/7=2/4/5+3/7=14/5+3/7=98+15/35=113/35=3 8/35

Answer 2

Х-3/7=2 8/10  8\10 сокращаем=4/5
Х=2 4/5+3\7  общий знаменатель 35
Х= 14/5+3/7=98/35+15/35=113/35=3 8/35
Х=3 8/35
Удачи!

Answer 3

Calculation of X minus three sevenths equals two and eight tenths

To calculate the value of X minus three sevenths equaling two and eight tenths, we need to solve the equation.

Let's break down the equation step by step:

1. X minus three sevenths: X - 3/7 2. Equals two and eight tenths: = 2 8/10

To solve this equation, we can convert the mixed number (two and eight tenths) into an improper fraction.

Two and eight tenths can be written as 2 8/10, which simplifies to 2 4/5.

Now, we have the equation:

X - 3/7 = 2 4/5

To solve for X, we need to isolate X on one side of the equation.

Adding 3/7 to both sides of the equation, we get:

X - 3/7 + 3/7 = 2 4/5 + 3/7

Simplifying the right side of the equation:

2 4/5 + 3/7 = (2 * 5 + 4)/5 + 3/7 = 14/5 + 3/7

To add fractions, we need a common denominator. The least common multiple of 5 and 7 is 35.

Converting both fractions to have a denominator of 35:

14/5 = (14 * 7)/(5 * 7) = 98/35 3/7 = (3 * 5)/(7 * 5) = 15/35

Now, we have:

X - 3/7 + 3/7 = 98/35 + 15/35

Combining the fractions on the right side of the equation:

98/35 + 15/35 = (98 + 15)/35 = 113/35

The equation becomes:

X = 113/35

Therefore, X minus three sevenths equals two and eight tenths is equivalent to X = 113/35.

Answer: X = 113/35
