To solve the equation _/_*_+_*_*_/_+_*_=100 using the numbers 1-9 in any order, you need to follow a specific order of operations: parentheses, exponents, multiplication, division, addition, and subtraction (PEMDAS). Let's break it down step by step:

First, we need to determine the multiplication and/or division operations in the expression. The equation has three multiplication operations represented by *, so we can start by focusing on those.

To achieve a sum of 100, we need to find three numbers that multiply together to give us a result close to 100. One way to do this is to consider the prime factors of 100, which are 2^2 * 5^2.

Using this information, we can determine the first multiplication operation as 2*25. The remaining two multiplication operations are yet to be determined.

Now, let's rewrite the equation with the values we have so far: _/(2*25) + _*_*_/(remaining numbers) + _*_=100.

Next, let's focus on the division operation represented by _/. The goal is to find a two-digit number divided by 50. The only number that fits this criteria is 100 divided by 50, which gives us 2.

Now, the equation becomes 2/(2*25) + _*_*_/ (remaining numbers) + _*_=100.

Next, we can look at the remaining multiplication operation represented by _*_*_. Our goal is to find three numbers that multiply together to get as close to 100 as possible. Since we've already used a 2 and a 25, we need to find one more factor. One possible option is 4*3*8=96.

Now, the equation becomes 2/(2*25) + 96/(remaining numbers) + _*_=100.

Lastly, we need to determine the value of the last multiplication operation represented by _*_. We have used 2, 25, and 96 already, so the remaining numbers are 3, 4, 5, 6, 7, 8, and 9. To get the sum to 100, we can use 5*9=45.

Now, let's substitute the values into the equation: 2/(2*25) + 96/(3*4*6*7*8*45)+ 5*_=100.

To find the value of the last blank, we can solve the equation: 2/(2*25) + 96/(3*4*6*7*8*45)+ 5*4=100.

Simplifying further, we have 2/50 + 96/(3*4*6*7*8*45)+ 5*4=100.

Evaluating each term, we get 0.04 + 96/362880 + 20 = 100.

Next, we find a common denominator for the fractions. The least common multiple of the numbers in the denominator is 362880.

Converting 0.04 to a fraction, we get 4/100, which simplifies to 1/25.

Re-writing the equation with the common denominator: 1/25 + (96*362880)/(362880*25) + 20 = 100.

Further simplifying, we have 1/25 + 96/362880 + 20 = 100.

Combining like terms, we get 1/25 + 96/362880 + 20/1 = 100.

To find the missing term and solve the equation, we can subtract the known terms from 100:

100 - (1/25 + 96/362880 + 20/1) = 0.

Therefore, the missing term is 0.

The complete equation then becomes: 2/(2*25) + 96/(3*4*6*7*8*45)+ 5*4=100.

Simplifying it further, we have 1/25 + 96/362880 + 20 + 0 = 100.

So, the solution to the equation _/_*_+_*_*_/_+_*_=100 using only numbers 1-9 in any order is:

1/25 + 96/362880 + 20 + 0 = 100.

2*_*_*5=100
