Question

Ursula wrote the sum 5.815 + 6.021 as a sum of two mixed numbers. What sum did she write?

Answer 1

Answer:

Ursula wrote 5.815 + 6.021 as $5 \frac{815}{1000}+6 \frac{21}{1000}$

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

$5.815+6.021=\frac{5815}{1000}+\frac{6.021}{1000}=\frac{5000+815}{1000}+\frac{6000+21}{1000}=5 \frac{815}{1000}+6 \frac{21}{1000}$

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 $5 \frac{815}{1000}+6 \frac{21}{1000}$
