05 07 04 09 _____ 00 10 _____ I have introduced leading zeros just for alignment (editor limitation). You cannot subtract 9 inches from 7 inches, so you borrow 1 foot from the 5 feet, so now you will have (12 + 7) 19 inches from which you can subtract 9 to get 10 inches. Since you borrowed 1 foot from 5 feet, it has only 4 feet left and if you subtract 4 from 4 you get zero. So the answer is 0 feet and 10 inches or simply 10 inches
Make your 6'9" into 5'21" Then subtract your feet (5'-2'=3') and next subtract your inches (21"-11"=10") For the final answer, join your intermediate answers together: 3'10"
0
8 feet, 10 inches
14 feet... without using a calculator !
change 100 into 99.99(10) - 17.935, subtract right ending digits...(10)-5 =5 etc to get 82. 065

10 feet because 10+5+10+5 = 30 feet
5 feet x 10 feet = 50 square feet.

5/10 - 4/10 = 1/10
