Question

decide whether nancy can make these arrays using all 20 tulips.

• 1 row of 20 tulips: yes
• 3 rows of 8 tulips: ?
• 5 rows of 4 tulips: ?
• 6 rows of 4 tulips: ?
• 20 rows of 1 tulip: ?
• 10 rows of 2 tulips: ?

Explanation:

Step1: Analyze "3 rows of 8 tulips"

To find the total number of tulips, multiply the number of rows by the number of tulips per row. So, \( 3 \times 8 = 24 \). Since \( 24>20 \), Nancy can't use all 20 tulips. So the answer is No.

Step2: Analyze "5 rows of 4 tulips"

Calculate the total: \( 5 \times 4 = 20 \). This equals the total number of tulips (20), so Nancy can use all 20 tulips. Answer is Yes.

Step3: Analyze "6 rows of 4 tulips"

Compute the total: \( 6 \times 4 = 24 \). Since \( 24>20 \), Nancy can't use all 20 tulips. Answer is No.

Step4: Analyze "20 rows of 1 tulip"

Total tulips: \( 20 \times 1 = 20 \). This matches the total, so answer is Yes.

Step5: Analyze "10 rows of 2 tulips"

Calculate: \( 10 \times 2 = 20 \). This equals 20, so answer is Yes.

Answer:

• 3 rows of 8 tulips: No
• 5 rows of 4 tulips: Yes
• 6 rows of 4 tulips: No
• 20 rows of 1 tulip: Yes
• 10 rows of 2 tulip: Yes
