Question

(7:7)•15+0:4•25-24(8:8)=​

Answer 1

(7:7)•15+0:4•25-24(8:8)=1•15+0•25-24•1=15+0-24=-19

Answer 2

Let's break down the expression step by step:

1. (7:7) means 7 divided by 7, which equals 1.
2. 15 + 0 = 15.
3. (0:4) means 0 divided by 4, which equals 0.
4. 25 - 0 = 25.
5. 24(8:8) means 24 multiplied by 8 divided by 8. Since 8 divided by 8 equals 1, this simplifies to 24 * 1 = 24.

Now, we can put it all together:

1 + 15 - 24 = -8

So, the result of the expression is -8.
