Question

1)1,5*10+2,08*45 2)12,08*100-75,6*11

Answer 1

1) To calculate 1.5 times 10, you simply multiply 1.5 by 10, which gives you 15.

Next, to calculate 2.08 times 45, you multiply 2.08 by 45. This gives you 93.6.

Finally, to find the sum of these two results, you add 15 and 93.6 together. The sum is 108.6.

So, the result of 1.5 times 10 plus 2.08 times 45 is 108.6.

2) To calculate 12.08 times 100, you multiply 12.08 by 100, which gives you 1208.

Next, to calculate 75.6 times 11, you multiply 75.6 by 11. This gives you 831.6.

Finally, to find the difference between these two results, you subtract 831.6 from 1208. The difference is 376.4.

So, the result of 12.08 times 100 minus 75.6 times 11 is 376.4.

Therefore, the final answer to the given expression is:

1) 1.5 * 10 + 2.08 * 45 = 108.6 2) 12.08 * 100 - 75.6 * 11 = 376.4
