Good evening ~

I have 2 questions.

Kelsey was assigned math homework. He was given 8 word problems to solve. He estimated that it would take him 5 mins. to solve each problem (THAT WOULD TAKE 40 MINS. FOR KELSEY TO COMPLETE HIS MATH HOMEWORK)

? HOW TO WRITE A MULTIPLICATION SENTENCE SHOWING SKIP COUNTING AS ANOTHER WAY TO SOLVE THIS PROBLEM?

?WHAT TWO FACTORS WOULD SHOW HOW IT COULD TAKE KELSEY AN HOUR TO COMPLETE 12 PROBLEMS AT 5 MINS. PER PROBLEM?

THANK YOU

Good evening! I can help you with your questions.

To write a multiplication sentence showing skip counting as another way to solve this problem, you need to understand that skip counting is a method of counting by a specific number, instead of counting by one. In this case, Kelsey estimates that it will take him 5 minutes to solve each problem.

Let's say Kelsey wants to find out how long it will take him to solve 8 problems. Instead of counting by one, he can skip count by 5s since it takes him 5 minutes per problem. To do this, he can start at 5 and keep adding 5 until he reaches 8. The multiplication sentence using skip counting would be:

5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 40

So, the multiplication sentence would be 8 x 5 = 40.

Now, let's move on to your second question. You mentioned that Kelsey estimated it would take him 5 minutes to solve each problem, and you want to know what two factors would show how it could take Kelsey an hour to complete 12 problems at 5 minutes per problem.

To find the factors, we need to determine the number of sets of 12 problems Kelsey could solve in an hour. Since each problem takes 5 minutes, we divide 60 minutes (an hour) by 5 minutes:

60 รท 5 = 12

So, Kelsey can solve 12 problems in an hour. Now, to find the factors, we can set up the multiplication sentence:

12 (number of sets of 12 problems) x 5 (minutes per problem) = 60 (total time in minutes)

The two factors are 12 and 5.

I hope this helps! Let me know if you have any further questions.
