Ursula wrote the sum 5.815 + 6.021 as a sum of two mixed numbers. a. what sum did she write. b. compare the sum of the mixed numbers to the sum of the decimals.

Sum of 5.815 + 6.021 = Mixed NumbersLet’s convert decimal numbers to mixed numbers

=>5.815 the decimal is .815 and 6.021 the decimal is .021

=> .815/1000

=> .021/1000

So the sum she wrote is:

=> 5 815/1000 + 6 021/1000 = 11 836/1000 in mixed numbers

Compare the sum of Mix number to the sum of the decimals

Mixed numbers Sum = 11 836/1000

Decimal numbers Sum = 11.836

Hope this helps!

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
