Part A: 1 solution
Part B:
4(3d −7) = −52
(4)(3d) + (4)(-7)= -52
12d + -28 = -52
12d - 28 = -52
12d - 28 + 28 = -52 + 28
12d = -24
12d/12 = -24/12
d = -2

Reducing the fractions, it is also true that:
Part A = 5/14 of the whole
Part B = 9/14 of the whole
It would be 7/48 or the decimal would be 0.15
