$1.00 because the first ounce is 0.40 then you have to times the other 3 ounce by 0.20 then u would have $1.00
Step-by-step explanation:
Length of title to board = (1/3) : (1/2) = 2 : 3.
Area of tile to board = (1/3)² : (1:2)² = 4 : 9.
It’s - ( - 3 ) because a negative times a negative equals a positive so it wouldn’t be - ( 3 ) because it would turn into a negative number and - ( - 3 ) would be positive
Find a common denominator...
1/5 = 7/35
7/35 = 7/35
6/25 = ... can't have 35 as a denominator. Not equivalent.
