Total length of the kitchen wall = 24 2/3 feet.
Let us convert 24 2/3 feet into improper fracion.
24 2/3 = (24*3+2)/3 = 74/3 feet.
Length of each strip = 1 3/4 feet.
Let us convert 1/3/4 feet in improper fracion.
1 3/4 feet = (1*4+3)/4 = 7/4 feet.
Total number of strips required = (Total length of the kitchen wall) ÷ (Length of each strip)
= 74/3 feet ÷ 7/4 feet.
Let us convert division sign into multiplication, we get
74/3 × 4/7.
Multiplying across, we get
296/21.
On dividing 296 by 21, we get 14.09 approximately.
14.09 represents more than 14.
So, we can round it to the next whole number, that is 15.
Therefore, 15 strips of border are needed.
