Question 1

2 3/5 * 6 1/15+1 1/14+1 39/73* (5 5/7-5 1/16)

Answer

Let's interpret the expression as: 2 3/5 × 6 1/15 + 1 1/14 + 1 39/73 × (5 5/7 − 5 1/16)

Step 1: Convert to improper fractions

2 3/5 = 13/5
6 1/15 = 91/15
1 1/14 = 15/14
1 39/73 = 112/73
(5 5/7) = 40/7
(5 1/16) = 81/16
(5 5/7 − 5 1/16) = 40/7 − 81/16 = 73/112

Step 2: Compute parts

(13/5) × (91/15) = 1183/75
(112/73) × (73/112) = 1

So the expression becomes: 1183/75 + 15/14 + 1

Step 3: Combine terms with common denominator Common denominator 1050:

1183/75 = 16562/1050
15/14 = 1125/1050
1 = 1050/1050

Total = (16562 + 1125 + 1050) / 1050 = 18737/1050

Final answer:

As an improper fraction: 18737/1050
As a mixed number: 17 887/1050 (gcd(887,1050) = 1)
Decimal: approximately 17.8448

Question 2

2 3/5 * 6 1/15+1 1/14+1 39/73* (5 5/7-5 1/16)

Answer

Let's interpret the expression as: 2 3/5 × 6 1/15 + 1 1/14 + 1 39/73 × (5 5/7 − 5 1/16) Step 1: Convert to improper fractions - 2 3/5 = 13/5 - 6 1/15 = 91/15 - 1 1/14 = 15/14 - 1 39/73 = 112/73 - (5 5/7) = 40/7 - (5 1/16) = 81/16 - (5 5/7 − 5 1/16) = 40/7 − 81/16 = 73/112 Step 2: Compute parts - (13/5) × (91/15) = 1183/75 - (112/73) × (73/112) = 1 So the expression becomes: 1183/75 + 15/14 + 1 Step 3: Combine terms with common denominator Common denominator 1050: - 1183/75 = 16562/1050 - 15/14 = 1125/1050 - 1 = 1050/1050 Total = (16562 + 1125 + 1050) / 1050 = 18737/1050 Final answer: - As an improper fraction: 18737/1050 - As a mixed number: 17 887/1050 (gcd(887,1050) = 1) - Decimal: approximately 17.8448
