Answer:
The question mark is 4/7.
Explanation:
Lets call the symbols Girl, Diamond, and Chest.
The second line has Diamond/Chest = 0
You can NEVER have zero on the bottom of a fraction. NEVER divide by 0. So this statement shows us that Diamond = 0
Now, look at the first statement.
Girl - Diamond = 5/7
Girl - 0 = 5/7
Girl = 5/7
We could use the third statement to find what the Chest equals. But let's skip it and save it to check our answer.
Look at the fourth statement.
Chest = 9/7 + Diamond
Chest = 9/7 + 0
Chest = 9/7
So far we found
Girl is 5/7 and
Chest is 9/7.
Do a check with the third statement.
2=Girl+Chest
2=5/7 + 9/7
2= 14/7
2= 2 That checks.
Lastly,
Chest - Girl = ?
9/7 - 5/7 = ?
4/7 = ?
