one half of 30 is 15 LOOPDOP says the question was 30 / 0.5 which = 60 same as 30 divided by 1/2 = 30 multiplied by 2/1 = 60
Because your calculator is broken. Seriously; 30 divided by half (0.5) is 60 and 60 + 10 = 70 So, 30 cut in half (30/2) is 15 but 30 DIVIDED BY half (30/0.5) is 60.
One and a half divided in half is 3/4
It is 60/2 = 30
To divide by a fraction, multiply by its reciprocal, In this instance, 30 / 1/2 = 30 x 2 = 60
