Question

 (0,98+7/10-0,27)*(0,69-0,49)

Answer 1

1. 7/10=0.7
2. 0.98+0.7-0.27=1.41
3. 0.69-0.49=0.2
4. 1.41*0.2=0.282

Answer 2

To calculate the expression (0.98 + 7/10 - 0.27) * (0.69 - 0.49), follow these steps:

Step 1: Perform the addition and subtraction inside the parentheses: (0.98 + 7/10 - 0.27) = (0.98 + 0.7 - 0.27) = 1.68 - 0.27 = 1.41

Step 2: Perform the subtraction inside the second set of parentheses: (0.69 - 0.49) = 0.20

Step 3: Multiply the results from Step 1 and Step 2: 1.41 * 0.20 = 0.282

So, (0.98 + 7/10 - 0.27) * (0.69 - 0.49) is equal to 0.282.
