Answer:
4/3
Step-by-step explanation:
Step 1: Cross-multiply.
135=a20
(13)*(20)=a*(5)
203=5a
Step 2: Flip the equation.
5a=203
Step 3: Divide both sides by 5.
5a5=2035
a=4/3
hope I'm right

Answer:
Step-by-step explanation:
3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles
make a proportion
(3/4) (7/4)
-------- = ------- cross multiply
1 x
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = (7/4) / (3/4)
x = 7/4 * 4/3
x = 7/3 or 2 1/3 miles <===
