\frac{12}{75}=\frac{12:3}{75:3}=\frac{4}{25}=\frac{4\times4}{25\times4}=\frac{16}{100}=0.16

For this case we have the following fraction:

\frac{12}{75}

Dividing the numerator and the denominator between 3 we have:

\frac{\frac{12}{3}}{\frac{75}{3}}

Then, multiplying the numerator and the denominator by 4 we have:

\frac{4}{25} =  \frac{4}{25} *\frac{4}{4}

We observe that we have a number divided by 100. Therefore, we must move the comma two units to the left:

\frac{16}{100} = 0.16

Answer:

The number in its decimal form is given by:

\frac{12}{75} = 0.16

All angles in a triangle add up to 180 so 180 - 60 = 120 then 180 - 155 = 25 then 25+65 = 90 that is the remaining angle but finally 180 - 90 = 90 is the missing angle

Answer:

a. 1 1/8 b. 8/9

Step-by-step explanation:

You can set this up as a proportion to solve.  For part a. we know that 2/3 of the road is 3/4 mile long.  2/3 + 1/3 = the whole road, so we need how many miles of the road is 1/3 its length.  Set up the proportion like this:

\frac{\frac{2}{3} }{\frac{3}{4} } =\frac{\frac{1}{3} }{x}

Cross multiplying gives you:

\frac{2}{3}x=\frac{1}{3}*\frac{3}{4}

The 3's on the right cancel out nicely, leaving you with

\frac{2}{3}x=\frac{1}{4}

To solve for x, multiply both sides by 3/2:

\frac{3}{2}*\frac{2}{3}x=\frac{1}{4}*\frac{3}{2} gives you

x=\frac{3}{8}

That means that the road is still missing 3/8 of a mile til it's finished.  The length of the road is found by adding the 3/4 to the 3/8:

\frac{3}{4}+\frac{3}{8}=\frac{6}{8}+\frac{3}{8}=\frac{9}{8}

So the road is a total of 1 1/8 miles long.

For b. we need to find out how much of 1 1/8 is 1 mile:

1 mile = x * 9/8 and

x = 8/9.  When 1 mile of the road is completed, that is 8/9 of the total length of the road completed.
