Answer 1

Ответ: А) 1 4/7

Пошаговое объяснение:

Answer 2

а)6-4*3/7=2*3/7=6/7

б)2*5/9=10/9=1,1/9

в)2,8/9+15/6=2,48/54+135/54=2,193/54=5,32/54                   это без умножить

в)2*8/9+15/6=16/9+15/6=96/54+135/54=231/54                       это с умножить

г)4,1/3-1,4/5=4,5/15-1,12/15=2,8/15

Answer 3

Let's simplify each expression step by step:

А) 6 - 4 + 3/7 Step 1: Subtract 4 from 6: 6 - 4 = 2 Final answer: 2 + 3/7

Б) 2 + 5/9 No further simplification is possible for this expression. Final answer: 2 + 5/9

В) 2 8/9 + 15/6 Step 1: Convert the mixed number to an improper fraction: 2 8/9 = (2 * 9 + 8)/9 = 26/9 Step 2: Simplify the expression: 26/9 + 15/6 Step 3: Find a common denominator, which is 18 (9 and 6 have 18 as their common multiple). 26/9 = (26/9) * (2/2) = 52/18 15/6 = (15/6) * (3/3) = 45/18 Step 4: Add the fractions: 52/18 + 45/18 = (52 + 45)/18 = 97/18 Step 5: Convert the improper fraction back to a mixed number (if possible): 97/18 = 5 7/18 Final answer: 2 8/9 + 15/6 = 5 7/18

Г) 4 1/3 - 1 4/5 Step 1: Convert the mixed numbers to improper fractions: 4 1/3 = (4 * 3 + 1)/3 = 13/3 1 4/5 = (1 * 5 + 4)/5 = 9/5 Step 2: Simplify the expression: 13/3 - 9/5 Step 3: Find a common denominator, which is 15 (3 and 5 have 15 as their common multiple). 13/3 = (13/3) * (5/5) = 65/15 9/5 = (9/5) * (3/3) = 27/15 Step 4: Subtract the fractions: 65/15 - 27/15 = (65 - 27)/15 = 38/15 Step 5: Convert the improper fraction back to a mixed number (if possible): 38/15 = 2 8/15 Final answer: 4 1/3 - 1 4/5 = 2 8/15

To summarize: А) 6 - 4 + 3/7 = 2 + 3/7 Б) 2 + 5/9 = 2 + 5/9 В) 2 8/9 + 15/6 = 5 7/18 Г) 4 1/3 - 1 4/5 = 2 8/15
