The sign at an amusement park reads, "You must be 36 inches tall to go on this ride." To be admitted to this ride, how many feet tall must a person be? (Enter numeric value only.)

First step is to convert the numbers into approximate decimals.

4/17=0.235

4/12=0.333

3/7=0.429

3/6=0.500

From the conversions above, 0.5 is the largest number among the four decimals. Then, it follows that 3/6 is the largest number.

First convert the mixed fractions into improper fractions as follows

\(3 2/5=\frac{\left(5\ast3\right)+2}{5}=\frac{15+2}{5}=\frac{17}{5}\)

\(3 1/6=\frac{\left(6\ast3\right)+1}{6}=\frac{18+1}{6}=\frac{19}{6}\)

Then, multiply the

As a mixed fraction 95/18 becomes 5 5/18

A ratio of the form a:b=c:d is converted to a proportion as

\(\frac{a}{b}=\frac{c}{d} \)

where b and d are not equal to zero. Now applying the same concept to 7:10=21:X yields,

\(\frac{7}{10}=\frac{21}{X}\)

Find the value of X by cross-product

\(7X=21\ast10\)

Divide both sides by 7

\(\frac{7X}{7}=\frac{210}{7} X=30 \\Thus,\ the value\ of \ X is \ 30. \)

The ratio 17:1000=X:10 can be written in proportion as:

\(\frac{17}{1000}=\frac{X}{10}\)

The value of X is determined by cross-products

\(17\ast10=1000X\)

170=1000X

Divide both sides by 1000

\(\frac{170}{1000}=\frac{1000X}{1000}\)

0.17=X

Thus, the value of X is 0.17
