Which value would make the statement true? StartFraction 2 Over question mark EndFraction greater-than StartFraction 4 Over 12 E
Romashka-Z-Leto [24]

Answer:

4

Step-by-step explanation:

Given the expression 2/? > 4/12, to find the value of ? that will make the expression true, we will cross multiply first

On cross multiplying:

2×12 > 4 × ?

24 > 4 × ?

Divide both sides by 4

24/4 > 4×?/4

6 > ?

This means that ? < 6

The answer will be a value that is less than 6. According to the option, the only value less than 6 is 4. Hence the correct answer is 4.
