you dont cuz your trying to make 20 or 19 out of an 8 and 3 if u calculate it
8+1+1+1=11
18, 19, 20
4 tens + 9 ones 3 tens + 19 ones 2 tens + 29 ones 1 ten + 39 ones 49 ones.
19 + 24 + 20 = 63/3 = 21 The average of the three numbers is 21.
4/20 + 15/20 = 19/20
Expressed as a proper fraction in its simplest form, 3/5 + 1/4 is equal to 17/20 or seventeen twentieths.
That is an A. You got 19 out of 20.
19, 20, 21
20
19, 20, and 21
18, 19, 20
you can't
There are 20 tens in 200 ones. This is because 200 divided by 10 equals 20. Each group of ten consists of ten ones, so you can make 20 groups of ten from 200 ones.
