Answer 1

$153 - 30.6 + 47 - 9.4 = 160$

Answer 2

To calculate the expression you provided:

15.3 * 10 - 2 * 15.3 + 10 * 4.7 - 2 * 4.7

We can follow the order of operations (PEMDAS/BODMAS) to solve it step by step:

First, we perform the multiplication and division from left to right:

15.3 * 10 = 153 2 * 15.3 = 30.6 10 * 4.7 = 47 2 * 4.7 = 9.4

The expression now becomes:

153 - 30.6 + 47 - 9.4

Next, we perform the addition and subtraction from left to right:

153 - 30.6 = 122.4 122.4 + 47 = 169.4 169.4 - 9.4 = 160

So the result of the expression is 160.
