To multiply, we multiply the digit in the ones place of 7 by 5000, which is 0. Then we multiply the digit in the tens place of 7 by 5000, which is 5 and add a 0 to get 50,000. So the answer is 35,000. To multiply a whole number by a number less than 10, we can start by multiplying the ones place and then moving on to the tens place, hundreds place, etc. 
7 multiplied by 0 is 0, so we can skip the ones place. 
7 multiplied by 5 is 35, so we write down 5 in the thousands place and carry over 3 to the tens of thousands place. 
7 multiplied by 1 is 7, plus the carried over 3 equals 10, so we write down 0 in the hundreds of thousands place and carry over 1 to the millions place. 
So the final answer is 35,000.
