Answer 2

Answer:

200 Tens + 80 Tens + 500 Tens = 78 Hundreds

Step-by-step explanation:

Given

200 tens + 80 tens + ___________________ = 78 hundreds

78 Hundreds = 78 x 100 = 78,00 = 780 Tens

200 Tens + 80 Tens = 280 Tens

780 Tens - 280 Tens = 500 Tens

200 x 10 + 80 X 10 + 500 X 10 = 78 X 100

ie 2000 + 800 + 5000 = 7800
