Пошаговое объяснение:

3/7+8 2/3=9/21+8 14/21=9 2/21

9 2/21-2/10=9 20/210-42/210=8 94/105

Answer 3

To solve the expression 3/7 + 8 2/3 - 2/10, you can break it down step by step. First, let's add the fractions:

3/7 + 8 2/3 = 3/7 + (8 + 2/3)

Now, let's add 8 and 2/3:

8 + 2/3 = 24/3 + 2/3 = (24 + 2)/3 = 26/3

So, the expression becomes:

3/7 + 26/3 - 2/10

Now, we need to find a common denominator for these fractions, which is 210:

(3/7) * (30/30) + (26/3) * (70/70) - (2/10) * (21/21) = 90/210 + 1820/210 - 42/210

Now, we can add the fractions with a common denominator:

(90 + 1820 - 42) / 210 = 1868/210

Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(1868/2) / (210/2) = 934/105

So, 3/7 + 8 2/3 - 2/10 is equal to 934/105.

Answer 4

To solve this expression, you need to perform the addition and subtraction operations step by step. Here's how you can do it:

1. Add the fractions 3/7 and 2/10:

   3/7 + 2/10

   To add these fractions, you need to find a common denominator. In this case, the least common denominator is 70.

   Convert both fractions to have a denominator of 70:

   (3/7) * (10/10) = 30/70 (2/10) * (7/7) = 14/70

   Now, add the fractions:

   30/70 + 14/70 = 44/70

2. Next, add the result from step 1 (44/70) to the whole number 8:

   44/70 + 8

   To add the fraction and the whole number, you can convert the whole number to a fraction with a denominator of 70:

   8 = 8/1

   Now, you can add the fractions:

   44/70 + 8/1 = 44/70 + 560/70

   44/70 + 560/70 = 604/70

3. Finally, simplify the fraction:

   To simplify the fraction, find the greatest common divisor (GCD) of 604 and 70, which is 2.

   Divide both the numerator and denominator by 2:

   (604/2) / (70/2) = 302/35

So, 3/7 + 8 2/3 - 2/10 = 302/35.
