Question

(11-9 1/2):0,003. ____________________. 4;05-3 13/20)*1;25

Answer 1

Ответ:

500

0,5

Пошаговое объяснение:

(11 - 9 1/2) : 0,003

сначала выполним действие в скобке

(11 - 9 1/2) : 0,003 = 1 1/2 : 0,003 = 1,5 : 0,003 = 1500 : 3 = 500

(4,05 - 3 13/20) * 1,25

сначала выполним действие в скобке

(4,05 - 3 13/20) * 1,25 = (81/20 - 73/20) * 1,25 = 8/20 * 1,25 = 4/10 * 1,25 = 0,4 * 1,25 = 4 * 0,125 = 0,5

Answer 2

Let's break down the expression step by step:

1. (11 - 9 1/2):

   • First, subtract 9 1/2 from 11.
   • 11 - 9 1/2 = 1/2

2. (1/2) / 0.003:

   • Next, divide 1/2 by 0.003.
   • (1/2) / 0.003 = 166.67 (rounded to two decimal places)

3. 4;05 - 3 13/20:

   • Subtract 3 13/20 from 4;05 (assuming the semicolon is used as a separator for minutes and seconds, and the fraction is in minutes).
   • 4;05 - 3 13/20 = 0;51 7/20

4. 0;51 7/20 * 1;25:

   • Finally, multiply 0;51 7/20 by 1;25.
   • First, convert both numbers to decimal fractions:
     • 0;51 = 0.51 (in decimal form)
     • 1;25 = 1.25 (in decimal form)
   • Now, multiply them:
     • 0.51 * 1.25 = 0.6375

So, the final result is approximately 0.6375.
