Answer:
129$
Step-by-step explanation:
774 / 6 = 129$
It's easiest to divide. If you don't have access to a calculator, you can find the answer in your head by breaking down the problem.
You know that 6 * 100 will give you 600... so we know its more than 100. We'd have 174 remaining to account for.
174 / 6 is 29. Add that 100 to the 29 and we get 129.
Mental math is gained through experience, so keep going at it and you'll get there.
