Oh, dude, math time! So, 200 grams is like 0.2 kilograms, right? And if it's 20 bucks per kilogram, you just gotta do some quick maffs and multiply 0.2 by 20. So, like, the cost would be 4 bucks. Easy peasy, chocolate squeezy!
Kaitlin Deasia and Aisha share 126 sweets in the ratio 2 3 4. How many sweets do they each get?
To find the total number of parts in the ratio, we add the parts together: 2 + 3 + 4 = 9 parts. To determine the value of each part, we divide the total number of sweets by the total number of parts: 126 sweets / 9 parts = 14 sweets per part. Finally, we multiply each person's share by their corresponding ratio part: Kaitlin gets 2 parts x 14 sweets = 28 sweets, Deasia gets 3 parts x 14 sweets = 42 sweets, and Aisha gets 4 parts x 14 sweets = 56 sweets.
What percent of 20 is 4?
4 is 20 percent of 20. 20 percent is equal to .20, so .20 x 20 = 4
