Answer 1

Вот, ДЕРЖИ) надеюсь, понятно)

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition, and Subtraction) step by step:

Step 1: Simplify the expression inside the parentheses first. 5/8 - 8/3 = (5/8) - (8/3) To subtract these fractions, we need a common denominator, which is 24. (5/8) - (8/3) = (15/24) - (64/24) = (-49/24)

Step 2: Now, we have the expression as follows: 2 1/3 : (-49/24) - 2 * 1 3/7

Step 3: Convert mixed numbers to improper fractions: 2 1/3 = (32 + 1)/3 = 7/3 1 3/7 = (71 + 3)/7 = 10/7

Step 4: Perform the multiplication: 2 * 10/7 = 20/7

Step 5: Now, we have the expression as follows: (7/3) : (-49/24) - 20/7

Step 6: Invert the divisor (-49/24) and change the division to multiplication: (7/3) * (-24/49) - 20/7

Step 7: Multiply the fractions: (7 * -24) / (3 * 49) - 20/7 = -168 / 147 - 20/7

Step 8: Simplify the fraction -168/147: -168/147 = (-8 * 21) / (7 * 21) = -8/7

Step 9: Now we have the expression as follows: -8/7 - 20/7

Step 10: Combine the fractions: (-8 - 20)/7 = -28/7 = -4

So, the complete solution is -4.
