10.5 ÷ 1.5 = <u>7 scoops needed</u>
Okie, so, each cm that measures across the pond is equivalent to 2ft
1cm=2ft
so if we have 3 cm
we would do 3x2
3x2=6
The diameter of the pond is 6 ft<span />
Answer:
20 20/27

<em>Additional comment</em>
The first two numbers can be written as a difference and a sum:
= (3 -1/3)(3 +1/3)(2 1/3)
= (3·3 -1/3·3 +3·1/3 -1/3·1/3)(2 1/3)
= (9 -1/9)(2 +1/3) = 9·2 +9·1/3 -1/9·2 -1/9·1/3 = 18 +3 -6/27 -1/27
= 20 20/27
