3/5 of 30 = (3 * 30) / 5 = 90/5 = 18
Prime factorisation of 18 = 2*3*3 Prime factorisation of 30 = 2*3*5 Then 1/18 = 5*1/5*18 = 5*90 (using the prime factor of 30 that is not in 18) and 1/30 = 3*1/3*30 = 3*90 (using the extra prime factor of 18 that is not in 30) So 1/18 + 1/30 = 5/90 + 3/90 = 8/90 = 4/45
30/5/3 = 30 x 3/5 = 18
It is: 18/30 = 3/5 in its simplest form
18/30=3/5
18/30 = 18 ÷ 30 = 0.6 Alternatively: 18/30 = (6×3)/(6×5) = 3/5 = 0.6 (known, or 3/5 = 3 ÷ 5 = 0.6).
3/5 of 30 = (3 * 30) / 5 = 90/5 = 18
18:30 = 3:5
Prime factorisation of 18 = 2*3*3 Prime factorisation of 30 = 2*3*5 Then 1/18 = 5*1/5*18 = 5*90 (using the prime factor of 30 that is not in 18) and 1/30 = 3*1/3*30 = 3*90 (using the extra prime factor of 18 that is not in 30) So 1/18 + 1/30 = 5/90 + 3/90 = 8/90 = 4/45
30/5/3 = 30 x 3/5 = 18
3/5 of 30 = 3*30/5 = 3*6 = 18
It is: 18/30 = 3/5 in its simplest form
18/30=3/5
For 18, 2 and 3 For 30 and 60, 2, 3 and 5
3/5 x 30 = 18(Divide 30 by 5, = 6. And you want 3 of the 5ths; 3 x 6, = 18)
3x5x6 = 90LCM of 18 and 30 = 90 Prime factorization of:18 = 2 * 3 * 330 = 2 * 3 .....* 5===========LCM=2 *3 * 3 * 5 = 90
Because: 5*18 = 90 and 3*30 = 90
