Question

31•0,01 4•0,5 2,9•10 50•0,02

Answer 1

31•0,01=0.31 4•0,5=2
2,9•10=29
50•0,02 =1

Answer 2

Let's calculate the results of these multiplications:

1. 31 * 0.01 = 0.31
2. 4 * 0.5 = 2
3. 2.9 * 10 = 29
4. 50 * 0.02 = 1

So, the results are:

1. 31 * 0.01 = 0.31
2. 4 * 0.5 = 2
3. 2.9 * 10 = 29
4. 50 * 0.02 = 1
