21+3
or using all the numbers:
21 + (3*(2-1))
You cannot make 24 using only the digits 3, 1, 8, and 8.
5x5=25 25-1=24
8 x (1 + 1) + 8 = 24
The GCF is 1.The GCF of 14, 21 and 24 is 1.
1, 2 and 21 when added.
you make a common denominator first so that it is 7/8 = 21/24 and 1/3 = 8/24 so 21/24 + 8/24 = 29/24 or 1.28033333....
9 +16 -1 = 24
6/(1-3/4)=24
(9-4-1)*6=24
5x5=25 25-1=24
You can make 24 rectangles of 1 x 1 tiles each.
9 - 1 = 8 2 + 1 = 3 8 x 3 = 24
