Question

4*(-17)*2,5 0,2*68*1/2

Answer 1

4*(-17)*2,5=-17*10=-170
0,2*68*½=68* ¹/10=6,8

Answer 2

Let's solve the expressions step by step:

1. 4 * (-17) * 2.5: First, multiply -17 by 4: -17 * 4 = -68

Next, multiply -68 by 2.5: -68 * 2.5 = -170

So, 4 * (-17) * 2.5 equals -170.

2. 0.2 * 68 * 1/2: First, multiply 0.2 by 68: 0.2 * 68 = 13.6

Next, multiply 13.6 by 1/2 (which is the same as dividing by 2): 13.6 * 1/2 = 6.8

So, 0.2 * 68 * 1/2 equals 6.8.
