Question

-12.6+8 1/2 - 7 1/4 +12 3/5 - 45.8+7.25

Answer 1

-12,6 + 8 1/2 - 7 1/4 + 12 3/5 - 45,8 + 7,25 =

= -12,6 + 8,5 - 7,25 + 12,6 - 45,8 + 7,25 =

= -4,1 - 7,25 + 12,6 - 45,8 + 7,25 =

= -11,35 + 12,6 - 45,8 + 7,25 =

= 1,25 - 45,8 + 7,25 =

= -44,35 + 7,25 =

= -37,3

Ответ: -37,3

Answer 2

To solve this expression, let's break it down step by step:

1. $-12.6 + 8 \frac{1}{2}$ $= -12.6 + 8 + \frac{1}{2}$ $= -4.6$ (adding 8 to -12.6 and 1/2)

2. $-4.6 - 7 \frac{1}{4}$ $= -4.6 - 7 - \frac{1}{4}$ $= -11.85$ (subtracting 7 and 1/4 from -4.6)

3. $-11.85 + 12 \frac{3}{5}$ $= -11.85 + 12 + \frac{3}{5}$ $= 0.3$ (adding 12 to -11.85 and 3/5)

4. $0.3 - 45.8$ $= -45.5$ (subtracting 45.8 from 0.3)

5. $-45.5 + 7.25$ $= -38.25$ (adding 7.25 to -45.5)

So, the result of the given expression $-12.6 + 8 \frac{1}{2} - 7 \frac{1}{4} + 12 \frac{3}{5} - 45.8 + 7.25$ is $-38.25$.
