Given: 315/1575. Write the prime fractorization of the numerator and the denominator, then write the fraction in lowest terms.

The prime factorization of the numerator, 315, is 5 x 3 x 3 x 7. That of the denominator, 1575 is 5 x 5 x 3 x 3 x 7. To convert the fraction to its lowest form, cancel all the factors that appear to both the numerator and denominator. We will be left with 1/5.

Answer:

A) $T=\frac{-20}{4}$

B) T = -5 °C

Step-by-step explanation:
