What is 1735/1000 written as a decimal?
Marat540 [252]

Answer:

\frac{1735}{1000} as a decimal is 1.735.

Step-by-step explanation:

To convert a fraction into a decimal, you first have to put the fraction into simplest form.

1. Simplest form

\frac{1735}{1000} = \frac{347}{200}\\\

To do this you must find a number you can equally divide both numbers by.

That number in this situation, 5.

1000/5= 200\\1735/5= 347\\1735:1000 = 347:200\\\frac{1735}{1000} =\frac{347}{200}

Now you must make this simplest formed fraction into a mixed number.

2. Simplest form into Mixed number

\frac{347}{200}= 1\frac{147}{200}

To do this you see how many times the denominator, the bottom number of the fraction, goes into the numerator, the upper part of the fraction.

Since 200 x 2 = 400 and since 400 > 347 this means...

200 goes into 347, once.

Finally, subtract and divide.

Remember put the whole number in front of the mixed number, before the decimal

3. Subtract, divide, decimalize

147/200= 0.735\\\\1\frac{147}{200}= 1.735

Hopes this helps you!

Have a good afternoon!

Check the picture below.

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ -2}}\quad ,&{{ 5}})\quad 
%   (c,d)
&({{ -1}}\quad ,&{{ 1}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{1-5}{-1-(-2)}\implies \cfrac{1-5}{-1+2}
\\\\\\
\cfrac{-4}{1}\impliedby\stackrel{slope~of}{PQ}

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ -1}}\quad ,&{{ 1}})\quad 
%   (c,d)
&({{ 7}}\quad ,&{{ 3}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{3-1}{7-(-1)}\implies \cfrac{3-1}{7+1}
\\\\\\
\cfrac{2}{8}\implies \cfrac{1}{4}\impliedby \stackrel{slope~of}{QR}

now, two lines who meet at a perpendicular angle, have a negative reciprocal slope of each other, to make it short, if you multiply their slopes, you should get -1 as the product, if they're indeed perpendicular.

\bf \stackrel{PQ}{-\cfrac{4}{1}}\cdot \stackrel{QR}{\cfrac{1}{4}}\implies -1

low and behold, they're indeed perpendicular, thus that angle is indeed a right-angle.
