Yes, as long as you do it to the denominator too. Say you have 10/15. To simplify the numerator you have to find something you can divide both by 10 and 15, which in this case, will be 5. So 10 by 5 is 2 and 15 by 5 is 3. So your answer would be 2/3.
You split 75 into 5 pieces and each piece is 15 so the answer is 15.

1, 3, 5, 15
Divide it be 3: 15/3 = 5
divide both numbers by their common factor (5). 15 divide by 5 is 3 25 divide by 5 is 5 So...... 3 over 5
equivalent fraction of 10 and 15 if you divide = 2/3 10 ÷ 5 = 2 15 ÷ 5 = 3
I would think a number only increases if divided by something less than 1 but greater than 0. If you divide something by 5 it would become less and decrease 10/5=2 5/5=1 but 15/ 1/2 = 30 10/ 1/4 = 40

This is all about factorising. Firstly yo have to find the biggest number that will go into both 15 and 75. 15 goes into both 15 and 75. Divide both numbers by 15, (15/15=1) (75/15=5) Therefore the ratio in its lowest terms is 1:5 If you can not recognise that 15 is the highest common factor straight off then look for smaller ones each time. e.g. divide by 5. Ratio = 3:15 divide new ration by 3. Ratio = 1:5
15 out 24 in simplest form is 5 out of 8 because when you divide 15 by 3 you have to divide 24 by 3 to. so its 5 out of 8
You split 75 into 5 pieces and each piece is 15 so the answer is 15.
If you mean 1/5 of 15 is 3 it is because 5 will divide into 15 exactly 3 times
