3 ft = 36 inches. So 3 ft / 18 in = 36 in/18 in = 1/2
It simplify to 1
3/42 divide top and bottom by 3 and you get 1/14
18/42 = 3/7
18/5 or 3 and 3/5
1/3
It simplifies to 1/4
3 ft = 36 inches. So 3 ft / 18 in = 36 in/18 in = 1/2
It simplify to 1
HCF(6, 18) = 6 so divide both by 6. 6/18 = 6/6 over 18/6 = 1 over 3 = 1/3
to simplify it you need to find a number which goes into both 3 and 18. In this case, it's 3. You divide the top and bottom of the fraction by 3 which gives you 1 over 6. 1/6th is the same fraction as 3/18th but is the simplest form.
3/42 divide top and bottom by 3 and you get 1/14
18 over 48 simplified is 3 over 8
3 over 4
18/42 = 3/7
No.
18/5 or 3 and 3/5
