It is 2 11/20.
1 whole and 1 over 10
4 3/10 - 2 4/5 = 43/10 - 14/5 = 43/10 - 28/10 = 15/10 = 1 whole 1 over 2
There are 40 of them because 40/10 = 4
There are 10 tenths in one whole, so to find out how many tenths make up two wholes, you would multiply 10 tenths by 2 wholes, which equals 20 tenths. Therefore, two wholes consist of 20 tenths.
ten
There are 40 tenths in four wholes. Since one whole is equivalent to ten tenths, you multiply the number of wholes (4) by 10 to get 40 tenths.
63/11 - 310/11 = 26/11 or 24/11
If One whole equals 10/10 then 5 holes would equal 50/10 Therefore there are 50 tenths in five holes.
10
15 fifths. Because 5/5 (1) times 3 = 15/5. 1 whole = 5 fifths 2 wholes = 10 fifths 3 wholes = 15 fifths
20
45/10 - 38/10 = 7/10
