Hello. In order to complete this question, you must have your graph, and it seems it's not there.
the amount of gold present is - 9/10 of an ounce of gold
from this gold they have to split into groups of 1/6 ounce each
so we have to divide 9/10 ounce in to groups of 1/6
for this we have to divide 9/10 by 1/6

when dividing fractions we mutiply the first fraction by the reciprocal of the second fraction
reciprocal of 1/6 is - 6/1

so the number of groups that can be made is 5 whole groups with 0.4 ounce of gold remaining
the whole number of groups that can be made - 5
Start at 4.
So far you have: 4
Now you go 7 units left. Going left means a subtraction. Going 7 units left means subtracting 7.
So far you have: 4 - 7
The result is -3.
The subtraction is:
4 - 7 = -3
Everything you need to do for this question is everything you do to one side you do it to the other
