73, every number is in the same range except 73
Answer:
13
Step-by-step explanation:
Given the expression;
2 1/3 : 4 1/3 = 7 : x
Wea re to look for x;
Convert to improper fractions;
7/3 : 13/3 = 7:x
7/3 * 3/13 = 7/x
7/13 = 7/x
Cross multiply
7x = 13 * 7
7x = 91
x = 91/7
x = 13
Hence the unknown value is 13
Find the unit rate for each

Top:
(-1/2 +1)(1/2 -1)(1+1)
= (1/2) (-1/2)(2)
= -1/2
so
-1/2 / 1/2)
= -1/2 x 2
= -1
answer is -1
