105. I'm a 5th grader; girl; 11 years old, and I sliced this problem. You can too if I can. it's called PEMDAS:Parenthese Exponents Multiplicayion Division Addition Subtraction. Yeah math brain no with I'm the math brain here. And every where! :);)
multiply feet by 12 and add inches; then minus inches. Example: 2 feet 2 inches minus 5 inches = 26-5 = 21 inches
7feet 4inches
12 feet 3 inches minus 4 feet 5 inches equals 7.83333333 feet or 7 feet 10 inches.
That leaves you with just six inches.
To subtract 8 inches from 3 feet, first convert 3 feet into inches. Since 1 foot equals 12 inches, 3 feet is 36 inches. Now, subtract 8 inches from 36 inches, which equals 28 inches. Therefore, 3 feet minus 8 inches is 28 inches, or 2 feet and 4 inches.
8 ft 8 inches
There are 12 inches in one foot. Therefore, 12 feet is equal to 12 x 12 = 144 inches. Subtracting 42 from this gives 144 - 42 = 102 inches.
convert feet to inches knowing that 1 foot = 12 inches 15 ft 10 in = 14 feet 22 inches 14 ft 22 in minus 11 ft 11 inches = 3 feet 11 inches
You need to know the equivalents of yards and feet and inches. There are 3 feet in a yard, and there are 12 inches in a foot. So that means there are 36 inches in a yard. 36-12= 24 inches left. That's 2 feet.
7 feet 3 inches.
12 feet, 8 inches
12 feet, 6 inches
