If you divide 537 in to 12 groups. each group would have 44 cookies and you would have 9 left.
The perimeter is 16.2. Let me know if you need me to show you how I got this
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.
1/5 = x/1100
5x = 1100
x = 1100 ÷ 5
x = 220
So 220 people named blue as fav.
3/10 = x/1100
3x = 1100
x = 1100 ÷ 3
x = 366.6666.... = 367
So 367 people chose red
