Question

0,25:4+15,3:5+12,4:8+0,15:30 4,912:16+(18,305:7+0,0368:4)

Answer 1

Ответ: 1. 4,6775; 2. 2,9312.

Пошаговое объяснение:

1. 0,25 : 4 + 15,3 : 5 + 12,4 : 8 + 0,15 : 30 = 4,6775

   1) 0,25 : 4 = 0,0625;              5) 0,0625 + 3,06 = 3,1225;

   2) 15,3 : 5 = 3,06;                   6) 3,1225 + 1,55 = 4,6725;

   3) 12,4 : 8 = 1,55;                    7) 4,6725 + 0,005 = 4,6775;

   4) 0,15 : 30 = 0,005;

2. 4,912 : 16 + (18,305 : 7 + 0,0368 : 4) = 2,9312

    1) 4,912 : 16 = 0,307;              4) 0,307 + 2,615 = 2,922;

    2) 18,305 : 7 = 2,615;             5) 2,922 + 0,0092 = 2,9312.

    3) 0,0368 : 4 = 0,0092;

Answer 2

Let's break down the given expressions step by step:

1. 0,25:4 + 15,3:5 + 12,4:8 + 0,15:30: To solve this expression, we need to perform the divisions first: 0,25 divided by 4 = 0,0625 15,3 divided by 5 = 3,06 12,4 divided by 8 = 1,55 0,15 divided by 30 = 0,005 Now, we can add these results: 0,0625 + 3,06 + 1,55 + 0,005 = 4,6775

2. 4,912:16 + (18,305:7 + 0,0368:4): Again, let's start by performing the divisions inside the parentheses: 18,305 divided by 7 = 2,615 0,0368 divided by 4 = 0,0092 Now, we can calculate the sum inside the parentheses: 2,615 + 0,0092 = 2,6242 Finally, we perform the division outside the parentheses: 4,912 divided by 16 = 0,307 Adding the results together: 0,307 + 2,6242 = 2,9312

Therefore, the results of the given expressions are as follows:

1. 0,25:4 + 15,3:5 + 12,4:8 + 0,15:30 = 4,6775
2. 4,912:16 + (18,305:7 + 0,0368:4) = 2,9312
