Multiply <br> (-3/4) x (-2/9)

xeze [42]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

When multiplying fractions, you simply multiply numerator by numerator and denominator by denominator, and if possible, you later simplify the answer.

$\frac{-3}{4} * \frac{-2}{9} = \frac{6}{36}$

$\frac{6}{36} / 6 = \frac{1}{6}$

Lily drove 354 miles in 6 hours. On average, how fast did she drive in hours per mile?

vagabundo [1.1K]

Answer: $\dfrac{1}{59}\ \text{hours per mile}$

Step-by-step explanation:

Given : Distance traveled by Lily= 354 miles

Time= 6 hours

Then,

$\text{LIly's rate in hours per mile}=\dfrac{6\text{ hours}}{354\text{ mile}}\\\\=\dfrac{1}{59}\ \text{hours per mile}$

Hence, the required speed of Lily = $\dfrac{1}{59}\ \text{hours per mile}$
