Question

(1,545/1.5-1)*2 2/3+0.5*4/15

Answer 1

(1,545/1,5-1)*2 2/3+0,5*4/15=16/75

1,545/1,5=1,03

1,03-1=0,03

0,03*2 2/3=3/100*8/3=24/300=0,08

0,5*4/15=5/10*4/15=2/15

0,08+2/15=8/100+2/15=24/300+40/300=64/300=16/75

Answer 2

Let's break down the expression step by step:

1. 1545 / 1.5 - 1 First, divide 1545 by 1.5, which is 1030. Then, subtract 1 from 1030, which is 1029.

2. 2/3 + 0.5 * 4/15 First, multiply 0.5 by 4/15, which is 2/15. Then, add 2/3 and 2/15. To add fractions, you need a common denominator, which in this case is 15. So, you can convert 2/3 to have a denominator of 15 by multiplying both the numerator and denominator by 5, which gives you 10/15. Now, you can add 10/15 and 2/15 to get 12/15.

Now, you have two results:

1. 1545 / 1.5 - 1 = 1029
2. 2/3 + 0.5 * 4/15 = 12/15

These results can be simplified:

1. 1029
2. 12/15 can be further simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3: (12/3) / (15/3) = 4/5

So, the final results are:

1. 1029
2. 4/5
