Answer:
Ursula wrote 5.815 + 6.021 as [tex]5 \frac{815}{1000}+6 \frac{21}{1000}[/tex]
Solution:
Given, Ursula wrote the sum 5.815 + 6.021 as a sum of two mixed numbers.
We have to find What sum did she write?
Decimals can be written as fractions with denominators that are powers of 10
[tex]5.815+6.021=\frac{5815}{1000}+\frac{6.021}{1000}=\frac{5000+815}{1000}+\frac{6000+21}{1000}=5 \frac{815}{1000}+6 \frac{21}{1000}[/tex]
We could simplify the fractions further more, but then the denominators would be different, so leave the fractions as they are.
Hence Ursula wrote 5.815 + 6.021 as [tex]5 \frac{815}{1000}+6 \frac{21}{1000}[/tex]
