Answer:
19
Step-by-step explanation:
1. Subtract and divide. 9 - 3 is 6, and 6 divided by 1/3 is 18, because whenever you divide by a fraction, you multiply by the reciprocal.
2. Add. 18 + 1 is 19.
The easiest way to do this is to start with the power of 5 that is just under 219.
125 would be the closest power of 5
Now subtract 125 from 219 = 94
=====================
The highest power of 5 closest to 94 is 25. You have to multiply 25 * 3 to get a number close enough to 94 that leaves a remainder under 25
94 - 75 = 19
=======================
19 - 3 * 5 = 4 Same argument as above.
219_10 = 1334_5
