This is simple subtraction to get the answer in millimetres. 20-10 gives you 10mm of a distance between both. You can simplify this answer by stating that this is also equal to 1 centimetre.
Yes, if you simplify them down you will get the same ratio. 1:4
No, because if you simplify them down you get 4:3 and 6:5, therefore not equal.
Expressed as a ratio in its simplest form, by dividing the antecedent and consequent by 2, 10:4 is equal to 5:2 or five to two.
4/10 = 2/5
Both fractions are equivalent, as they simplify to 3/4 and 4/5 respectively. Therefore, neither fraction is bigger than the other; they are equal.
4/10 but if you want to simplify it . . . 2/5
10-4 = 1/104 = 0.0001
Yes, 4/10 simplifies to 2/5
76/10 which you can simplify if you so wish.
