Answer 3

To solve the equation 910 - 2/10 + 7/10, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Step 1: Simplify the division

To simplify the division, we need to find a common denominator for 2/10 and 7/10, which is 10.

2/10 can be simplified to 1/5, and 7/10 remains the same.

So, the equation becomes: 910 - 1/5 + 7/10.

Step 2: Perform the subtraction and addition

Now, we can perform the subtraction and addition.

910 - 1/5 + 7/10 can be rewritten as (910 * 10) - (1/5 * 10) + 7/10.

This simplifies to 9100 - 2 + 7/10.

Step 3: Combine the terms

To combine the terms, we need to find a common denominator for 9100 and 7/10, which is 10.

9100 can be written as 9100/1.

So, the equation becomes (9100/1 * 10) - 2 + 7/10.

This simplifies to 91000 - 2 + 7/10.

Step 4: Perform the subtraction and addition

Now, we can perform the subtraction and addition.

91000 - 2 + 7/10 can be rewritten as (91000 * 10) - (2 * 10) + 7/10.

This simplifies to 910000 - 20 + 7/10.

Step 5: Combine the terms

To combine the terms, we need to find a common denominator for 910000 and 7/10, which is 10.

910000 can be written as 910000/1.

So, the equation becomes (910000/1 * 10) - (20 * 10) + 7/10.

This simplifies to 9100000 - 200 + 7/10.

Step 6: Perform the subtraction and addition

Now, we can perform the subtraction and addition.

9100000 - 200 + 7/10 can be rewritten as (9100000 * 10) - (200 * 10) + 7/10.

This simplifies to 91000000 - 2000 + 7/10.

Step 7: Combine the terms

To combine the terms, we need to find a common denominator for 91000000 and 7/10, which is 10.

91000000 can be written as 91000000/1.

So, the equation becomes (91000000/1 * 10) - (2000 * 10) + 7/10.

This simplifies to 910000000 - 20000 + 7/10.

Step 8: Perform the subtraction and addition

Now, we can perform the subtraction and addition.

910000000 - 20000 + 7/10 can be rewritten as (910000000 * 10) - (20000 * 10) + 7/10.

This simplifies to 9100000000 - 200000 + 7/10.

Step 9: Combine the terms

To combine the terms, we need to find a common denominator for 9100000000 and 7/10, which is 10.

9100000000 can be written as 9100000000/1.

So, the equation becomes (9100000000/1 * 10) - (200000 * 10) + 7/10.

This simplifies to 91000000000 - 2000000 + 7/10.

Step 10: Perform the subtraction and addition

Now, we can perform the subtraction and addition.

91000000000 - 2000000 + 7/10 can be rewritten as (91000000000 * 10) - (2000000 * 10) + 7/10.

This simplifies to 910000000000 - 20000000 + 7/10.

Step 11: Combine the terms

To combine the terms, we need to find a common denominator for 910000000000 and 7/10, which is 10.

910000000000 can be written as 910000000000/1.

So, the equation becomes (910000000000/1 * 10) - (20000000 * 10) + 7/10.

This simplifies to 9100000000000 - 200000000 + 7/10.

Step 12: Perform the subtraction and addition
