Write a decimal that is 1/10 of 0.9
Mkey [24]

The <em>correct answer</em> is:

0.09

Explanation:

First off, we can write 0.9 as a fraction. Reading this, we would say "nine tenths"; this means the number in fraction form is 9/10.

The word "of" in mathematics means we multiply. Thus when we take 1/10 "of" 9/10, we multiply the two:

1/10(9/10)

To multiply fractions, multiply the numerators and multiply the denominators:

1/10(9/10) = (1*9)/(10*10) = 9/100

Converting this back to a decimal, we read 9/100 as "nine one-hundredths"; this means decimal form is 0.09.

So first thing you need to understand is that ABC and AFE are congruent triangles. This means we can find the other angles, based on ABC:

Angle FAE = 26.56505118 degrees
Angle AEF = 63.43494882 degrees

Angles ECD and DEC are both 45 degrees

Now, we can find the angles in ACE:

AEC = 71.56505118 degrees
ECA = 71.56505118 degrees
CAE = 36.86989764 degrees

sweet [91]
<span>If you want to convert 1.4 into a fraction, you can do it like this:
<span>
1 <span>equals to </span>1/1 <span>and </span>0.4 <span>equals to </span>4/10 <span>which simplifies to </span>2/5.
<span>The result is </span>1 2/5.

If you want to write the ratio of 1.4/7 in the simplest form, you can do this using the following steps:

1.4/7 = 1 2/5 / 7 = 7/5 / 7 = 7/5 * 1/7 = 1/5 = 0.2

The correct result would be 1/5.</span></span>
