The powers of the primes are: 4, 2, 1 and 1 So the number of divisors are (4+1)*(2+1)*(1+1)*(1+1) = 5*3*2*2 = 60
.4 × .5 = .2 = 1/5
2/5
-5+1= 4 -5 times 1 = -5
1/2
1 and 1/4 times 2 is (5/4) x 2 = 10/4 = 5/2 = 2 and 1/2 or 2.5 in decimal
1/4 * 2+1/2 = 1/4*5/2 = 5/8
5/3 x 4/5 x 3/2 = 60/30 = 2
The powers of the primes are: 4, 2, 1 and 1 So the number of divisors are (4+1)*(2+1)*(1+1)*(1+1) = 5*3*2*2 = 60
4/5 of 2 is 1 3/5
.4 × .5 = .2 = 1/5
2/5
-5+1= 4 -5 times 1 = -5
4+1/5 x 2 = 8 2/5
If you mean: (4-5) times (1-3) then it is 2
4/5 x 2 is 1 3/5 or 1.6
1/2
