Question

(5 13/21×2,1):(14,1-2,3)​

Answer 1

(5 13/21*2,1):(14,1-2,3)=(118/21*2,1):11,8=(118/21*21/10):11,8=11,8:11,8=1

Answer 2

To solve the expression (5 13/21 × 2,1) : (14,1 - 2,3), we need to follow the order of operations, which is typically remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition, and Subtraction).

Let's break down the expression step by step:

Step 1: Perform the division inside the parentheses first. (14,1 - 2,3) = 14,1 - 2,3 = 11,8

Step 2: Perform the multiplication. (5 13/21 × 2,1) = (118/21 × 2,1) = (5.619 × 2,1) = 11.7999 (rounded to four decimal places)

Step 3: Divide the result obtained in Step 2 by the result obtained in Step 1. 11.7999 ÷ 11,8 ≈ 1.00008 (rounded to five decimal places)

Therefore, the final result is approximately 1.00008.
