Question

Amber wants to know how many blocks of each color will be needed for a tapestry on the number of 40. How many blocks of each color will she make? Explain why she needs to identify a new color for this tapestry

Answer 1

Amber will make the tapestry using 3 red blocks and 1 blue block.

Explanation:

In this question, you need to identify the prime factors of 40. For that you must completely divide 40 using the prime numbers mentioned in the question i.e. 2,3,5,7 and 11 until there is no remainder (your answer is 1).

Step 1: Divide 40 by 2. 40/2=20.

Step 2: Divide 20 by 2. 20/2=10.

Step 3: Divide 10 by 2. 10/2=5.

Step 4: Divide 5 by 5. 5/5=1.

Now we need to see how many prime factors did we obtain. The prime factors of 40 are 2,2,2,5. This indicates that Amber will make the tapestry using 3 red blocks and 1 blue block since 2 corresponds to a red colored block and 5 corresponds to blue colored block.
