Question

4*(18:9)*7-64:8= 80-(25:5+9) : 2-13= 2*9-36:(3+8:6) = 4+4:2+(30-15) : 3=

Answer 1

4+4:2+(30-15):3=7,2*9-36:(3+8:6)=0,80-(25:5+9):2-13= 60,4*(18:9)*7-64:8=48

Answer 2

Let's break this down step by step:

4*(18:9)7-64:8 = 4(2)*7 - 8 = 56 - 8 = 48

So, now we have:

80 - (25:5+9) : 2 - 13 = 2*9 - 36:(3+8:6) = 4+4:2+(30-15) : 3

Next, let's simplify the expression inside the parentheses:

25:5+9 = 5+9 = 14

Now, let's simplify the expression inside the second set of parentheses:

3+8:6 = 3 + (8/6) = 3 + (4/3) = (9/3) + (4/3) = 13/3

So, now our expression looks like this:

80 - 14 : 2 - 13 = 2*9 - 36:(3+(4/3)) = 4+4:2+15/3

Let's simplify the expression 14:2:

14:2 = 7

Now, let's simplify the expression 36:(3+(4/3)):

3+(4/3) = (9/3) + (4/3) = 13/3

36:(13/3) = 36 * (3/13) = (36/13)*3 = 108/13

So, now our expression looks like this:

80 - 7 - 13 = 18 - (108/13) = 4+2+5

Let's simplify the expression (108/13):

108/13 = 8.3077 (rounded to four decimal places)

So, now our expression looks like this:

80 - 7 - 13 = 18 - 8.3077 = 11.6923

Finally, let's simplify the expression 4+2+5:

4+2+5 = 11

Therefore, the final answer is:

11.6923
