Led Question 1. How did you compute sums of dollar amounts that were not whole numbers? For example,
how did you compute the sum of $5.89 and $1.45? Use this example to explain your strategy.
Your answer

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

Step-by-step 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

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

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
