2. Write each expanded addition as a whole number, and then write the number in words: a) \( 60000000+4000000+400000+10000+3000+500+30+9 \) b) \( 900000000+90000000+4000000+300000+7000+400 \) \( +60+6 \) c) \( 8000+90+3+100000+5000000+40000+60000000+ \) d) \( 600+900000000 \) d \( 600000000+4+30000000+9000 \)

Certainly! Let's break down each expanded addition, calculate the whole number, and then express it in words. --- ### **a) \( 60,000,000 + 4,000,000 + 400,000 + 10,000 + 3,000 + 500 + 30 + 9 \)** **Calculation:** \[ 60,000,000 + 4,000,000 = 64,000,000 \] \[ 64,000,000 + 400,000 = 64,400,000 \] \[ 64,400,000 + 10,000 = 64,410,000 \] \[ 64,410,000 + 3,000 = 64,413,000 \] \[ 64,413,000 + 500 = 64,413,500 \] \[ 64,413,500 + 30 = 64,413,530 \] \[ 64,413,530 + 9 = 64,413,539 \] **Whole Number:** 64,413,539 **In Words:** Sixty-four million, four hundred thirteen thousand, five hundred thirty-nine. --- ### **b) \( 900,000,000 + 90,000,000 + 4,000,000 + 300,000 + 7,000 + 400 + 60 + 6 \)** **Calculation:** \[ 900,000,000 + 90,000,000 = 990,000,000 \] \[ 990,000,000 + 4,000,000 = 994,000,000 \] \[ 994,000,000 + 300,000 = 994,300,000 \] \[ 994,300,000 + 7,000 = 994,307,000 \] \[ 994,307,000 + 400 = 994,307,400 \] \[ 994,307,400 + 60 = 994,307,460 \] \[ 994,307,460 + 6 = 994,307,466 \] **Whole Number:** 994,307,466 **In Words:** Nine hundred ninety-four million, three hundred seven thousand, four hundred sixty-six. --- ### **c) \( 8,000 + 90 + 3 + 100,000 + 5,000,000 + 40,000 + 60,000,000 \)** **Calculation:** \[ 60,000,000 + 5,000,000 = 65,000,000 \] \[ 65,000,000 + 40,000 = 65,040,000 \] \[ 65,040,000 + 100,000 = 65,140,000 \] \[ 65,140,000 + 8,000 = 65,148,000 \] \[ 65,148,000 + 90 = 65,148,090 \] \[ 65,148,090 + 3 = 65,148,093 \] **Whole Number:** 65,148,093 **In Words:** Sixty-five million, one hundred forty-eight thousand, ninety-three. --- ### **d) \( 600 + 900,000,000 \)** **Calculation:** \[ 900,000,000 + 600 = 900,000,600 \] **Whole Number:** 900,000,600 **In Words:** Nine hundred million six hundred. --- ### **e) \( 600,000,000 + 4 + 30,000,000 + 9,000 \)** **Calculation:** \[ 600,000,000 + 30,000,000 = 630,000,000 \] \[ 630,000,000 + 9,000 = 630,009,000 \] \[ 630,009,000 + 4 = 630,009,004 \] **Whole Number:** 630,009,004 **In Words:** Six hundred thirty million, nine thousand four. --- Feel free to ask if you need further clarification on any of these!
