Write each rate as a fraction in lowest terms
15 feet in 30 seconds
15/30 = 1/2
20 to 30 feet/sec
To write the rate "15 feet in 30 seconds" as a fraction in lowest terms, we can write it as:
\[ \frac{15 \text{ feet}}{30 \text{ seconds}} \]
To simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and denominator, which is 15. By dividing both the numerator and denominator by 15, we get:
\[ \frac{15 \div 15 \text{ feet}}{30 \div 15 \text{ seconds}} = \frac{1 \text{ foot}}{2 \text{ seconds}} \]
Therefore, the rate "15 feet in 30 seconds" as a fraction in lowest terms is:
\[ \frac{1 \text{ foot}}{2 \text{ seconds}} \]
To write the rate of 15 feet in 30 seconds as a fraction in lowest terms, we need to simplify the numerator and denominator.
First, let's write the rate as a fraction: 15 feet / 30 seconds.
To simplify the fraction, we can look for the greatest common factor (GCF) of the numerator and denominator. In this case, both 15 and 30 are divisible by 15.
So, we can divide both the numerator and denominator by 15:
(15 feet / 30 seconds) / 15 = (1 foot / 2 seconds).
Therefore, the rate of 15 feet in 30 seconds as a fraction in lowest terms is 1 foot / 2 seconds.
