Answer 3

Calculation 1: 7 + 1/3 × 60 + 19 + 1/3 × 60 - 6 + 2/3 × 60

To calculate this expression, we can follow the order of operations (PEMDAS/BODMAS) and perform the calculations step by step.

Step 1: Calculate 1/3 × 60 - 1/3 × 60 = 20

Step 2: Calculate 2/3 × 60 - 2/3 × 60 = 40

Now, let's substitute the calculated values back into the original expression:

7 + 20 + 19 + 20 - 6 + 40

Step 3: Perform addition and subtraction from left to right:

7 + 20 = 27 27 + 19 = 46 46 + 20 = 66 66 - 6 = 60 60 + 40 = 100

Therefore, the result of the expression 7 + 1/3 × 60 + 19 + 1/3 × 60 - 6 + 2/3 × 60 is 100.

Calculation 2: 13 + 1/7 × 28 + 19 + 5/7 × 28 - 2 + 6/7 × 28

Following the same steps as in Calculation 1, let's calculate this expression:

Step 1: Calculate 1/7 × 28 - 1/7 × 28 = 4

Step 2: Calculate 5/7 × 28 - 5/7 × 28 = 20

Step 3: Calculate 6/7 × 28 - 6/7 × 28 = 24

Now, let's substitute the calculated values back into the original expression:

13 + 4 + 19 + 20 - 2 + 24

Step 4: Perform addition and subtraction from left to right:

13 + 4 = 17 17 + 19 = 36 36 + 20 = 56 56 - 2 = 54 54 + 24 = 78

Therefore, the result of the expression 13 + 1/7 × 28 + 19 + 5/7 × 28 - 2 + 6/7 × 28 is 78.
