c. $60+4 de 7= total

$60/3=$20= 1 de 7

$20*7=$140=total

Answer 2

12. 180 billetes × 4/9 = 80 billetes de $500

180 - 80 = 100

100 × 3/5 = 60 billetes de $200

100 - 60 = 40 billetes de $100

80 × 500 = $40,000

60 × 200 = $12,000

40 × 100 = $4,000

40,000 + 12,000 + 4,000 = $56,000

13. a) 280 ÷ 2/3 = 140 × 3 = $420

b) 9/9 - 5/9 = 4/9

320 ÷ 4/9 = 80 × 9 = $720

c) 7/7 - 4/7 = 3/7

60 ÷ 3/7 = 20 × 7 = $140
