2-make sense and persevere how can you estimate to check if your answer is reasonable? explain

Answer 1

Jamie starts with 875 building pieces, and after giving away a castle set with 257 pieces and acquiring a helicopter set with 229 pieces, he has 847 pieces. Estimation using rounding confirms that this answer is reasonable.

Step-by-step explanation:

Jamie originally has 875 building pieces. When Jamie gives away his castle set, which has 257 pieces, we subtract that number from his original total. Jamie's new total becomes 875 - 257 = 618 pieces. After giving away the castle set, Jamie buys the helicopter set, which has 229 pieces. To find out how many building pieces Jamie has now, we add the pieces from the helicopter set to his current total: 618 + 229 = 847 pieces.

To estimate and check if the answer is reasonable, we can use rounding. Jamie starts with about 900 pieces (rounding 875 to the nearest hundred), gives away about 300 pieces (rounding 257 up), and then adds about 200 pieces (rounding 229 down). Following this estimation, Jamie should have around 800 pieces, which is close to the exact answer of 847, indicating our calculation is reasonable.

Answer 2

Answer 1:

Total pieces left with Jamie = 618

Step-by-step explanation:

Given in the question is that Jamies has eight hundred and seventy-five building pieces. Out of that, he gave two hundred and fifty-seven pieces to his friend. Though after giving some pieces to his friend he bought two hundred and twenty-nine helicopters. Now to calculate the total number of pieces left with Jamie we need to minus the given from the obtained building pieces.

Total number of building pieces he has = 875

Number of castle pieces that he gave to a friend = - 257

Total pieces left with Jamie = 618

Answer 2:

As asked, yes it does make sense that the number of building pieces left with Jamie is six hundred and eighteen. To find a number of building pieces that he has left we had subtracted the total number of buildings to the number of castles gave equal the to a number of pieces left. Therefore, we put the values of total building pieces equal to 875, pieces of castle equal to 257 and finally we get the number of pieces left of building a puzzle that is 618. This proof the solution of the question and makes perfect sense for the reasoning.
