Express the recurring decimal 0.042 as a fraction in its simplest form.

rodikova [14]

Answer:

7/165

Step-by-step explanation:

This is a mixed recurring decimal (the zero is not repeating)

We take number after the decimal point 042

then we subtract the non repeating.In this case is 0 so we not subtract anything

This will be the numerator 42

Now ,the denominator:

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990 = 7/165

7:165 = 0.0424242......

Victor is measuring his bodily dimensions. his neck is 14.72 inches in circumference, and his forearm is 25.81 centimeters long.

Triss [41]

The length of his neck is longer than the length of his forearms by 44.86 %.

<h3>Calculations and Parameters:</h3>

Given:

Length of his neck = 14.72 inches

Length of his forearm = 25.81 cm

We know that:

1 inch = 2.54 cm

So, 14.72 inches = 14.72×2.54

=37.39 cm

So, the Length of his neck becomes 37.39 cm

So, the length of his neck is longer than the length of his forearms.

The difference between them is given by

37.39-25.81

=11.58 cm

so, the Percentage of change would be

11.58/25.81 * 100

=44.86%
