Answer 1

Ответ:

Пошаговое объяснение:

a) 2,7+ 2,7+ 2,7=2,7*3=8,1

б) 13,26 + 13,26 + 13,26 + 13,26 + 13,26=13,26*5=66,3

B) 0,83 + 0,83 + 0,83 + 0,83.=0,83*4=2,52

Answer in detail. 1) Replace addition with multiplication and calculate the result: a) 2.7 + 2.7 + 2.7; 5) 13.26 + 13.26 + 13.26 + 13.26 + 13.26; B) 0.83 + 0.83 + 0.83 + 0.83.​

To solve this problem, you need to use the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. For example, 2.7 + 2.7 + 2.7 can be written as 3(2.7), which is equal to 8.1. Similarly, 13.26 + 13.26 + 13.26 + 13.26 + 13.26 can be written as 5(13.26), which is equal to 66.3. And 0.83 + 0.83 + 0.83 + 0.83 can be written as 4(0.83), which is equal to 3.32. Therefore, the final answers are:

a) 2.7 + 2.7 + 2.7 = 3(2.7) = 8.1 5) 13.26 + 13.26 + 13.26 + 13.26 + 13.26 = 5(13.26) = 66.3 B) 0.83 + 0.83 + 0.83 + 0.83 = 4(0.83) = 3.32

I hope this helps you understand the problem better.
