Jake trips over his dog 40% percent of mornings. 25% of the time he trips, he drops his coffee. What percentage of mornings does he NOT drop his coffee?
Let's think: First multiply the chance of each event happening to find the chance they both happen: 40% * 25% = 10%. Then subtract that percentage from 100% to find the percentage of the time Jake doesn't drop his coffee: 100% - 10% = 90%.. The answer is: 90.

Aaron has some brothers. Bennett has 6 brothers. If the number of Bennett's brothers is two less than twice the number of Aaron's brothers, what is the number of Aaron's brothers?
Let's think: Twice the number of Aaron's brothers is 6 + 2 = 8. Aaron has 8 / 2 = 4 brothers.. The answer is: 4.

Anna wears a size 2. Her friend Becky wears a size three times larger than Anna's. Ginger wears a size twice Becky's size minus 4. What size does Ginger wear?
Let's think: First find what size Becky wears: 2 * 3 = 6. Then multiply that number by 2: 6 * 2 = 12. Then subtract 4 to find Ginger's size: 12 - 4 = 8.. The answer is: 8.

Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts. How many pairs of socks does he need to buy to double the number of individual items in his wardrobe?
Let's think:
First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t - shirts are individual items. Therefore there are 20 * 2 = 40 individual socks in 20 pairs of socks. Similarly, there are 5 * 2 = 10 individual shoes in 5 pairs of shoes. Therefore, Jonas has 40 + 10 + 10 + 10 = 70 individual items in his collection. To double this number, we perform 70 * 2 = 140. This means we need 140 - 70 = 70 new items to double the size. Since there are 2 individual socks in each pair, we take 70 / 2 = 35 new pairs of socks.. The answer is: 35.
