Sure! I'd be happy to help you with these questions. Let's break it down one by one:
1. To solve 19 2 1/4 + 3 15/16, we first add the whole numbers separately: 19 + 3 = 22. Then, we add the fractions separately: 1/4 + 15/16.
To add fractions, we need to find a common denominator. In this case, a common denominator is 16. So, we rewrite 1/4 as 4/16. Now, we can add the fractions: 4/16 + 15/16 = 19/16.
To summarize, 19 2 1/4 + 3 15/16 = 22 19/16.
2. Next, let's solve -5 7/12 + 10 3/4. Similar to the previous question, we add the whole numbers separately: -5 + 10 = 5. Then, we add the fractions: 7/12 + 3/4.
To add fractions, we need a common denominator. In this case, a common denominator is 12. So, we rewrite 3/4 as 9/12. Now, we can add the fractions: 7/12 + 9/12 = 16/12.
However, 16/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4. So, we get 4/3.
To summarize, -5 7/12 + 10 3/4 = 5 4/3.
3. Moving on to -3.5 + (-5.2), this is a simple addition of two decimal numbers. Just add them directly: -3.5 + (-5.2) = -8.7.
So, yes, -3.5 + (-5.2) equals -8.7.
4. Lastly, let's solve -304 + 9.1. Again, this is a simple addition of two decimal numbers. Just add them directly: -304 + 9.1 = -294.9.
So, no, -304 + 9.1 does not equal 6. It equals -294.9.
I hope these explanations were helpful! Let me know if there's anything else I can assist you with.
