PSLEHenry pushes two sticks, V and W, straight into the ground until the length of each stick that is above the ground is the same.
13 of V and
17 of W are in the ground. The length of V in the ground is 6 cm longer than the length of W in the ground. What is the total length of sticks V and W?
Fraction of Stick V above ground
= 1 -
13 =
23 Fraction of Stick W above ground
= 1 -
17 =
67 Heights of Sticks V and W above ground are the same.
23 V =
67 W
69 V =
67 W
Length of Stick V more than length of Stick W
= 9 u - 7 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Total length of Sticks V and W
= 9 u + 7 u
= 16 u
= 16 x 3
= 48 cm
Answer(s): 48 cm
