Mieko practiced shooting a basketball for 7/10 of her total practice time. during the other time, she practiced dribbling, if she practiced dribbling for 18 minutes, how many minutes did she practice shooting

It would be 42 min. Because if 3/10 of her time is don't shooting and that takes up 18 min then if you divide by 3 to get how many minutes would be 1/10 of her practice you can then multiply that number by 7 because there are 7 of those sections done for shooting. 18 divided by 3 is 6 and 6 times 7 equals 42. So the answer is 42

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
