6,25:5/3-2,5:1,5+7 1/2-8 1/3

Answer 1

Вот решение, в ответе получилось 1.25

Answer 2

Let's break down the expression and solve it step by step using the order of operations (PEMDAS):

6,25 : 5/3 - 2,5 : 1,5 + 7 1/2 - 8 1/3

Step 1: Convert mixed numbers to improper fractions

6,25 : 5/3 - 2,5 : 1,5 + 7 1/2 - 8 1/3

= 6 1/4 : 5/3 - 2 1/2 : 1 1/2 + 7 1/2 - 8 1/3

= (6 × 4 + 1) / 4 : 5/3 - (2 × 2 + 1) / 2 : (1 × 2 + 1) / 2 + (7 × 2 + 1) / 2 - (8 × 3 + 1) / 3

= 25 / 4 : 5/3 - 5 / 2 : 3 / 2 + 15 / 2 - 25 / 3

Step 2: Perform division first, then multiplication, and then addition/subtraction from left to right

= 6.25 : 1.67 - 2.5 : 1.5 + 7.5 - 8.33

= 3.74 - 1.67 + 7.5 - 8.33

= 1.24

Therefore, the final answer is 1.24.
