22. One kilometer is approximately 0.62 mile. What fraction represents this length?

bixtya [17]

Answer:

One kilometer is $\frac{31}{50}$ miles

Explanation:

To convert a decimal to a fraction:

1- Write the decimal as a fraction whose denominator is 1

2- Multiply both numerator and denominator by multiples of 10 to eliminate the decimal point

3- Simplify the fraction you have

Now, for the given problem:

The given decimal is 0.62, following the above steps:

Step 1:

$0.62 = \frac{0.62}{1}$

Step 2:

We have two digits after the decimal point, so to eliminate the decimal point, we will multiply the numerator and the denominator by 100

$0.62 = \frac{0.62}{1} * \frac{100}{100} = \frac{62}{100}$

Step 3:

We can note that, in the fraction obtained from step 2, both the numerator and the denominator are divisible by 2, so we simplify as follows:

$\frac{62}{100} = \frac{62/2}{100/2} =\frac{31}{50}$

Hope this helps :)

Sara is 5 ft 10inches y’all ? To the nearest centimeter how tall is sara? If 1 in equals 2.54 centimeters

Dahasolnce [82]

1 foot = 12 inches.

5 ft x 12 inches per foot = 60 inches.

60 inches + 10 inches = 70 inches.

Sara was 70 inches tall.

Now convert to centimeters:

70 inches x 2.54 centimeters per inch = 177.8 cm's.

Round to nearest centimeter = 178 cm's.
