Step-by-step explanation:
yo that's actually really sick
1) first step
in first place you must to Know how many feets are in a mile, it is given at the exercise ( 5280 feet = 1 mile)
now Winston's wi-fi has a range of 1 1/2 miles, it is necessary to transform to mile, then 1 + 1/2 = 3/2
establish the following relation 1 mile ____ 5280 feet
3/2 mile _____ x feet
x = 3/2mile ×5280 feet/ 1 mile = 7920 miles this is the range of the Winston 's wi-fi
2 ) second step
in order to know the relation of proportion you must divide the largest amount between the lowest
7960/ 3920 = 2
3960/ 7960 = 1 / 2⇒ 2×3960 = 1×7960, it means that the signals have the relation of 1 : 2, then the value of the range of Winston's signal <em>is twice ( 2) </em>the value of the range of isaac's signal, therefore the value of ratio is 2
<span>Let the number be x.
The quotient of negative 1 and the product of a number and 21 is -1/21x</span>
