If 1/3 of a number is 12, the number is 36.

(1/3)x = 12

x = 12/(1/3)

x = 12 * 3

x = 36

1/3x = 12
x = 12 divided by 1/3
x = 12 X 3
x=36

Let total length of pole = L
Portion beneath water = 1/3 L
Given portion beneath water = 50 cm
Set up equation
1/3 L = 50
Solve for L
L = 50 × 3 = 150 cm
Answer: Total length of pole = 150 cm, portion beneath water = 50 cm

Solution:
{1}/{3} × 12 = 4 { acres}
{1}/{4} × 12 = 3 { acres}
4 + 3 = 7 { acres}
12 - 7 = 5 { acres}
{5}/{12}
(a) Fraction of land unploughed = ( {5}/{12} )
(b) Acres of land unploughed = 5 acres.

Let total population = P
Men = 5/8 P
Children = 1/6 P
Women = P - (5/8 P + 1/6 P)
Express women in terms of P
Common denominator for 8 and 6 is 24
5/8 = 15/24, 1/6 = 4/24
Women = P - (15/24 P + 4/24 P) = P - 19/24 P = 5/24 P
5/24 P = 500
Solve for P
P = 500 × 24/5 = 2400
Find number of children
Children = 1/6 × 2400 = 400
Answer: 400 children

If the piece eaten on the fourth day weighed 12g, 96 grams did the whole cake weigh.
Solution
1/12 + 1/6 + 3/8 = 8/24 + 4/24 + 9/24 = 21/24

1 - 21/24 = 3/24

(3/24) * Whole Cake Weight = 12g

To find the whole cake weight:

Whole Cake Weight = 12g / (3/24) = 12g * (24/3) = 96g

Fractions given
Blue = 1/3
Green = 5/12
Red = 1/10
Yellow = the rest
Find the fraction for yellow
1/3 + 5/12 + 1/10
= 20/60 + 25/60 + 6/60
= 51/60
Yellow = 1 - 51/60
= 9/60
= 3/20
Use yellow information
(3/20) × Total = 108
3T/20 = 108
3T = 2160
T = 720
Find number of green pencils
(5/12) × 720 = 300
Answer: 300 green pencils
