Studdy Solution

STEP 1

Assumptions
1. The number 52 is represented using blocks, typically in a base-10 blocks system where 'longs' represent tens and 'cubes' represent ones.
2. To subtract 17 from 52 using blocks, we need to remove 1 long (which represents 10) and 7 cubes (which represent 7 ones).

STEP 2

Understand the representation of the number 52 in blocks.
- In a base-10 block system, 52 is represented by 5 longs (each representing 10) and 2 cubes (each representing 1). - Therefore, the representation of 52 is 5 longs and 2 cubes.

STEP 3

Identify the components of the number 17 that need to be subtracted from 52.
- The number 17 consists of 1 long (representing 10) and 7 cubes (representing 7 ones).

STEP 4

Determine the steps required to subtract 17 from 52 using blocks.
- To subtract 17, we need to remove 1 long and 7 cubes from the representation of 52.

STEP 5

Analyze if it is possible to directly remove 7 cubes from the 2 cubes that represent the ones in 52.
- Since there are only 2 cubes in the representation of 52, we cannot directly remove 7 cubes.

STEP 6

Realize the need to convert 1 long into 10 cubes to have enough cubes to subtract 7.
- To get enough cubes to subtract 7, we need to convert 1 long into 10 cubes. This is because we only have 2 cubes and we need to remove 7.

STEP 7

Combine the steps to model the subtraction of 17 from 52 using blocks.
- We need to take away 1 long (Step 4). - We need to convert 1 long into 10 cubes (Step 6). - Then, we can take away 7 cubes from the newly converted 10 cubes plus the 2 cubes we originally had (Step 5).

STEP 8

Conclude the necessary actions to model the problem 521752-17 using blocks.
- The correct actions are: A. Take away 7 cubes. B. Take away 1 long. C. Convert 1 long into 10 cubes. - Therefore, the answer is D. All of the above.
The actions needed to model the problem 521752-17 using blocks are to take away 7 cubes, take away 1 long, and convert 1 long into 10 cubes.
