2 : 2 2/3 + 1 4/5 × 3 1/3 - 2 5/6


Ответы на вопрос

2) 14/5*31/3 = 28 14/15
3) 3/11+ 28 14/15 = 29 34/165
4) 29 34/165 - 25/6= 24 13/330



2) 1 4/5 * 3 1/3 = 9/5 * 10/3 = 3/1* 2/1= 6
3) 3/4+ 6 = 6 3/4
4) 6 3/4-2 5/6 = 6 9/12 - 2 10/12 = 5 21/12 - 2 10/12 = 3 11/12



To solve the expression, we need to perform the operations in the correct order: multiplication and division before addition and subtraction. Let's break it down step by step:
Step 1: Convert all mixed fractions to improper fractions.
2 2/3 = (2 * 3 + 2) / 3 = 8 / 3 1 4/5 = (1 * 5 + 4) / 5 = 9 / 5 3 1/3 = (3 * 3 + 1) / 3 = 10 / 3 2 5/6 = (2 * 6 + 5) / 6 = 17 / 6
So the expression becomes:
8/3 + 9/5 × 10/3 - 17/6
Step 2: Perform multiplication and division.
To multiply, simply multiply the numerators together and the denominators together:
(9/5) × (10/3) = (9 * 10) / (5 * 3) = 90 / 15 = 6
Step 3: Perform addition and subtraction.
Now the expression becomes:
8/3 + 6 - 17/6
Step 4: Find a common denominator to add and subtract the fractions.
The common denominator for 3 and 6 is 6. We need to convert 8/3 to a fraction with a denominator of 6:
8/3 = (8 * 2) / (3 * 2) = 16 / 6
Now the expression becomes:
16/6 + 6 - 17/6
Step 5: Combine the fractions and perform the final subtraction.
(16/6) + 6 - (17/6) = (16 + 6 - 17) / 6 = 5/6
So the final result is 5/6.
