9. 1/18

10. 1/18

Here is how I got my answer for 9:

Step 1: Simply $9/54$ to $1/6$ . Which leaves us with $1/6$ - $1/9$

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator. By multiplying $6*3$ and $9*2$ . Which leaves us with $3/18$ - $2/18$ .

Step 4: Subtract 3 and two, giving you your answer: $1/18$

Here is how I got my answer for 10:

Step 1: Simplify $6/12$ to $1/2$ . Which leaves us with $1/2$ - $4/9$

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator by multiplying $2*9$ and $9*2$ . Which leaves us with $9/18 - 8/18$ .

Step 4: Subtract 9 and 8, giving you your answer: $1/18$

Answer:

36.7 ft

Step-by-step explanation:

Measurements for the sides of the canal is given as: 40 ft. and 16 ft.

You solve the above question using Pythagoras Theorem

The distance across the canal is calculated as:

√(40² - 16²)

= √(1344)

= 36.66060556 ft

Approximately = 36.7 ft

Therefore, the distance x across the canal = 36.7 ft
