Question

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

Answer 1

Ursula wrote 5.815 + 6.021 as
`5 (815)/(1000)+6 (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=(5815)/(1000)+(6.021)/(1000)=(5000+815)/(1000)+(6000+21)/(1000)=5 (815)/(1000)+6 (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 (815)/(1000)+6 (21)/(1000)`
