Question

,by what rational number should minus 7 upon 85 be subtracted to obtain one upon 17​

Answer 1

Answer:

There is a verb missing in the question, and it is essential.

I assume the missing verb is “divided”. To solve this, we need to understand that:

If [math]\frac{a}{b} = c[/math], then [math]\frac{a}{c} = b[/math].

What does that buy us? Well, we want to know what [math]b[/math] is such that [math]\frac{\frac{-7}{85}}{b} = \frac{1}{17}[/math]

To solve this, we can apply the above and get that [math]b = \frac{\frac{-7}{85}}{\frac{1}{17}}[/math]. This can be simplified to something nicer, I’ll leave that part of your homework to you.

Answer 2

Answer:

Step-by-step explanation:

let the required no be X

-7/85 × X = 1/17

-7X/85 = 1/17

-119X = 85

X = -85/119

X = -5/7

Hence, -5/7should -7/85 be multiplied to obtain 1/17
