malcom is organizing his bedroom. he found 6 jars filled with pennies. if each jar has 560 pennies, how many pennies does corey have in all?

Explanation:

Step1: Round 3,305,063 to nearest 1,000

Look at the hundreds digit (0). Since 0 < 5, we keep the thousands digit as is. So 3,305,063 rounded to nearest 1,000 is 3,305,000.

Step2: Round 5,382,619 to nearest 10,000

Look at the thousands digit (2). Since 2 < 5, we keep the ten - thousands digit as is. So 5,382,619 rounded to nearest 10,000 is 5,380,000.

Step3: Calculate 67,593 + 10,430

Add the two numbers: 67,593+10,430 = 78,023.

Step4: Calculate 42×18

Using area model: 42×18=(40 + 2)×(10+8)=40×10+40×8+2×10+2×8=400+320 + 20+16 = 756.

Answer:

• Rounded 3,305,063 to nearest 1,000: 3,305,000
• Rounded 5,382,619 to nearest 10,000: 5,380,000
• 67,593 increased by 10,430: 78,023
• Product of 42×18: 756
