Draw the results in the workspace below. There are _____________ ones How many ones are in each group? _____________ Each group contains _____________ ten and _____________ ones, or _____________. So, Gary needs to save _____________ each month. Check: Use multiplication to check your answer. _____________ Ă— 12 =$156

Answer: Gary needs to save $12 each month. Explanation: Given that, Gary is saving up to buy a trumpet for a band that costs$156.
He saves the same amount each month for 12 months.
Now, we will find how much money is for 15 ten blocks using the Base ten blocks.
Based on the given question steps,
You can not separate the hundreds of blocks into 12 groups, regroup them into tens.
So, there is 15 tens total.
Now, divide tens equally into 12 groups.
One ten in each group. There are still 3 tens and 6 ones that need to be divided.
Use the remaining tens and ones and regroup them as ones. Then divide the ones equally into 12 groups.
There are 36 ones.
In each group, 3 ones will be there.
Each group contains 1 ten and 3 ones, or 13.
So, Gary needs to save $13 each month. Use multiplication, and check our answer. i.e.,$13 x 12 = $156. Talk About It Question 1. In the activity, you started by placing 1 ten in each group. What will be the place value of the first digit of the quotient? Answer: Tens place will be the place value of the first digit of the quotient. Question 2. What would happen if the cost of the trumpet was$168? Would the amount saved each month increase or decrease?
Answer: The amount saved each month will be increased.

Question 3.
Mathematical PRACTICE Justify Conclusions Suppose Gary chose to save $156 for 13 months instead of 12 months. Will the amount he needs to save per month increase or decrease? Explain your answer. Answer: The amount he needs to save per month decreased because the base-ten blocks for$156 would now be spread out over 13 months instead of 12 months.

Practice It

Use models to find each quotient. Draw the equal groups.

i.e., 17 x 8 = 136.

Apply It

Question 8.
The average person eats an average of 26 pounds of bananas each year. How many years would it take a person to eat 104 pounds of bananas? Draw models to find the quotient.

Answer: A person takes 4years to eat 104 pounds of bananas.
Now, we will the quotient value models as,

Explanation: Given that,
The average person eats an average of 26 pounds of bananas each year.
Now, we will find out how many years would it take a person to eat 104 pounds of bananas.
So, the value is 104 and 26.
Divide it, to get the value.
i.e., 104/26 = 4
Therefore, A person takes 4years to eat 104 pounds of bananas.
Now, we can draw equal groups using the quotient value.
The value 104 is divided by 26, to get the quotient 4.
So, we can draw 4 one blocks. Like that, we will draw 26 groups.
i.e., 26 x 4 = 106.

Question 9.
A travel van holds 11 people. There are a total of 143 people signed up to take a trip to the zoo. How many vans are needed? Draw models to find the quotient.

The quotient value of model blocks is shown below,

Explanation: Given that,
A travel van holds 11 people.
There are a total of 143 people signed up to take a trip to the zoo.
Now, we will find out how many vans are needed.
So, the value is 143 and 11.
Divide it, to get the value.
i.e., 143/11 = 13
Therefore, 13 vans are needed.
Now, we can draw equal groups using the quotient value.
The quotient value is 13.
So, we can draw 13 blocks. Like that, we will draw 11 groups.
i.e., 13 x 11 = 143.

Question 10.
Mathematical PRACTICE Plan Your Solution Cheryl has a collection of sports cards and has 8 pages in the album. Each page of the album holds 14 sports cards. If she completely fills the album, how many total sports cards does she have? Draw models to find the dividend.

Answer: If she completely fills the album, she needs 112 total sports cards.
Now, we will draw models to the dividend value.

Explanation: Given that,
Cheryl has a sports card collection and 8 pages in the album.
Each page of the album holds 14 sports cards.
Now, we will find the total sports cards. If she completely fills the album.
So, the value is 14 and 8.
We will find the dividend value i.e., 14 x 8 = 112.
Therefore, she needs 112 total sports cards to fill the album completely.

Question 11.
Mathematical PRACTICE Use Math Tools The average person eats an average of 16 pounds of apples each year. How many years would it take a person to eat 144 pounds of apples? Draw models to find the quotient.

Answer: 9 years would take a person to eat 144 pounds of apples.
Now, draw the models to the quotient value.

So, 16 groups x 9 blocks= 144.
Explanation: Given that,
The average person eats an average of 16 pounds of apples each year.
Now, we will find out how many years would it take a person to eat 144 pounds of apples.
So, the values are 144 and 16.
