675 • 246=166050

167580-166050=1530

Answer 2

To solve the given expressions:

B) 3.44 : 0.4 + 24.56

First, perform the division: 3.44 : 0.4 = 8.6

Then, add the result to 24.56: 8.6 + 24.56 = 33.16

Therefore, the value of the expression is 33.16.

r) 684 · 245 - 675 • 246

First, multiply 684 by 245: 684 * 245 = 167,580

Then, multiply 675 by 246: 675 * 246 = 166,350

Finally, subtract the second result from the first: 167,580 - 166,350 = 1,230

Therefore, the value of the expression is 1,230.
