Your answer

Answer 1

Computing the sum of $5.89 and $1.45 we get: $7.34

Explanation:

We need to explain, how can we compute the sum of $5.89 and $1.45?

Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.

Computing the sum of $5.89 and $1.45

`\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34`

So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7

So, Computing the sum of $5.89 and $1.45 we get: $7.34
