Given 160 hawks and 70% of these 160 hawks were spotted last weekend. To solve this problem, take the decimal form of 70% which is 0.7 and multiply it with 160, 160 x 0.7 = 112
Therefore, the Raptor club spotted 112 hawks last weekend.
If you multiply 10 by 4 that gets you the area, but you need to find the surface so multiply the product by 7 and that gets you the surface which is 280
