Answer 2

It looks like you've provided a series of mathematical expressions that involve addition and subtraction of mixed numbers and decimals. Let's solve each one step by step:

2. 6 4/25 + 2.81 - 1 3/4

First, let's add the mixed numbers: 6 4/25 + 1 3/4 = 6 4/25 + 7/4 = (multiply 25 by 1 to have a common denominator) 6 4/25 + 25/4

Now, we can find a common denominator for the fractions: 6 4/25 + 25/4 = (multiply the first fraction by 4/4 to have a common denominator) 6 4/25 + 100/100 = 6 4/25 + 100/100

Now, combine the fractions: 6 4/25 + 100/100 = 6 104/100

Now, simplify the decimal part: 6 104/100 = 6.04

Finally, subtract 6.04 from 2.81: 2.81 - 6.04 = -3.23

So, the result is -3.23.

4. 41.7 - 8 3/5 + 2 1/4

First, subtract the mixed numbers: 41.7 - (8 3/5) = 41.7 - (8 + 3/5) = 41.7 - 8 - 3/5

Now, subtract the whole numbers: 41.7 - 8 = 33.7

Now, subtract the fractions: 33.7 - 3/5 = (multiply 5 by 7 to have a common denominator) 33.7 - 21/5

Now, combine the fractions: 33.7 - 21/5 = (convert 33.7 to a fraction with a common denominator of 5) 337/10 - 21/5

Now, find a common denominator: (337/10) - (42/10) = 295/10

Now, simplify the fraction: 295/10 = 29.5

Finally, add 2 1/4 to 29.5: 29.5 + 2 1/4 = 29.5 + 2.25 = 31.75

So, the result is 31.75.

6. 58.75 - 21 9/10 + 4 8/25

First, subtract the mixed numbers: 58.75 - (21 9/10) = 58.75 - (21 + 9/10) = 58.75 - 21 - 9/10

Now, subtract the whole numbers: 58.75 - 21 = 37.75

Now, subtract the fractions: 37.75 - 9/10 = (multiply 10 by 3.775 to have a common denominator) 377.5/10 - 9/10

Now, combine the fractions: (377.5/10) - (9/10) = 368.5/10

Now, simplify the fraction: 368.5/10 = 36.85

Finally, add 4 8/25 to 36.85: 36.85 + 4 8/25 = 36.85 + 4.32 = 41.17

So, the result is 41.17.
