You can write it just as given:
... (time spent in video games)/(time spent in television) = (10 minutes)/(1 hour)
However, the intent is to end with a pure number (no units), so we need to convert hours to minutes or vice versa. Most folks know that 1 hour is 60 minutes, so that is probably the easier conversion.
... = (10 minutes)/(60 minutes)
... = 10/60 . . . . . . . . . the units in numerator and denominator are the same, so cancel
... = 1/6 . . . . . . . . . . . .the fraction is reduced in the usual way
The ratio in simplest form is 1/6.

Answer:
Option A, 300 - 20w
Step-by-step explanation:
In a week, she withdraws $20
in w weeks, she will withdraw ; w × 20
= 20w
Balance = Initial amount - Amount withdrawn
= 300 - 20w
Answer:
Step-by-step explanation:
We have two sides; the Adjacent and the Hypotnuse
Meaning we will use Cos
Cos = A/H
Cos X = 16/19
Use the inverse of Cos to find the angle
X = cos-1 (16/19)
X = 0.45499141546
X = 0.45
