Answer:
3 2/10 - 1 4/10 = ?
32/10 - 14/10 = ?
18/10 = ?
1 8/10 = 1 4/5
but in decimal terms
both 1 8/10 and 1 4/5 are equal to 1.8
The statement is not always true.
For Example...
The LCM of 6 and 8 is not the product of the two numbers
6*8= 48
48 is not the LEAST common multiple
Multiples of 6 are...
6,12,18,24,30,36,42,48...
Multiples of 8 are....
8,16,24,32,40,48...
The least common multiple is 24 not 48 even though they are both common multiples.
It is 8 units.
2πr=16π
r=16π/2π
r=8.
