1. 1/6

3. 3/8
4 1/2
5.5/8


let say back lawn = 6
therefore front lawn = 1/3 * 6 =2
total = 6+2 = 8
now moved lawn= 1/2)*2 + 2/3)*6 = 5
therefore unmoved lawn = total - moved = 8 - 5 =3
fraction = unmoved / total = 3/8

hence C

Say back lawn = x, so front lawn = x/3

Total lawn = x + x/3 = 4x/3 ................ (i)

back lawn mowed = 2x/3 & front lawn mowed = x/6

Total mowed = 2x/3 + x/6 = 5x/6 .......... (ii)

Total Unmowed = (i) - (ii)

= 4x/3 - 5x/6 = x/2 ................... (iii)

Unmowed Fraction = (iii) / (i)

x/2 * 3/4x = 3/8 (Answer = C)

Fraction of unmoved lawn = Total un mowed lawn / Total Area
F - Front Lawn
B - Back Lawn

F = 1/3(B)

Total Area = F+B = 4F (or 4/3 B; lets keep it as 4F for simplicity)

Total un mowed = Remaining of Front + Remaining of Back;
"John mows 1/2 of his front lawn": so 1/2F remaining
"and mows 2/3 of his back lawn,": so 1/3 of B remaining; which is 1/3(3F) = F
Total un mowed = 3/2(F)

Fraction = \frac{3}{2}*F/4F = 3/8.

Ans: C
