Question

37:2целых3/17-17,8+1целых2/7

Answer 1

37 : 2 3/17 - 17,8 + 1 2/7 = 17/35

1) 37 : 2 3/17 = 37 : 37/17 = 37 * 17/37 = 17
2) 17 - 17,8 = - 0,8 = - 4/5
3) - 4/5 + 1 2/7 = 1 2/7 - 4/5 = 1 10/35 - 28/35 = 45/35 - 28/35 = 17/35

Пояснения:
2 целых 3/17 = (2*17+3)/17 = 37/17
0,8 = 8/10 = 4/5
4/5 = 28/35 - доп.множ. 7
2/7 = 10/35 - доп.множ. 5
1 целая 10/35 = 35/35 + 10/35 = 45/35

Answer 3

To simplify the given expression, let's break it down step by step:

1. Convert mixed fractions to improper fractions: 37: 2 целых 3/17 = 37 + 2 * (3/17) = 37 + 6/17 1 целых 2/7 = 1 + 2/7

2. Add the whole numbers and fractions separately: 37 + 6/17 - 17.8 + 1 + 2/7

3. Convert the decimal to a fraction: 17.8 = 17 + 8/10 = 17 + 4/5

Now, let's combine the whole numbers and fractions:

37 + 6/17 - (17 + 4/5) + 1 + 2/7

4. Perform the operations:

Step 1: Subtract the fractions first: 37 + 6/17 - 17 - 4/5 + 1 + 2/7

Step 2: Combine the whole numbers: (37 - 17 + 1) + 6/17 - 4/5 + 2/7

Step 3: Find a common denominator for the fractions (17 * 5 * 7 = 595): (21) + (6 * 35)/(17 * 35) - (4 * 119)/(5 * 119) + (2 * 85)/(7 * 85)

Step 4: Perform the operations further:

21 + 210/595 - 476/595 + 170/595

Step 5: Combine the fractions:

21 + (210 - 476 + 170)/595

Step 6: Perform the addition:

21 - 96/595

Step 7: Convert the improper fraction back to a mixed fraction:

21 - 96/595 = 20 + 499/595

So, the simplified expression is:

20 целых 499/595
