Answer:
39,375
Step-by-step explanation:
So we are going to multiply 375 by 105. First we are going to multiply five by five which =25 so we put our five nd carry out 2 over the seven.
2
375
<u> x 105
</u>
5
Then, we multiply 5 by 7 which =35 + 2 = 37. So we put our seven and carry our three.
32
375
<u>x 105
</u>
75
Next, we multiply 5 by 3 which is 15 + 3 = 18 so we put down our 18 becuase we cant carry the one to another number.
32
375
<u>x 105
</u>
1,875
Now, we put a zero before we start because each time we make a new line we have to add a zero first
375
<u>x 105
</u>
1,875
0
Now we can start multiplying again. So 0 x 5 = 0 so we put our next zero. Then 0 x 7 = 0, put another zero. then 3 x 0 = 0, put our last zero.
375
<u>x 105
</u>
1,875
0000
Okay, now time to multiply by one. Before we start because we started another new line we put 2 zeros because its our third line.
375
<u>x 105
</u>
1,875
0000
00
Now we may begin multiplying by 1. 1 x 5 = 5. Then, 1 x 7 = 7. Finally 3 x 1 = 3
375
<u>x 105
</u>
1,875
0000
37,500
Now we add up 1,875 + 37,500
1,875
<u> +37,500</u>
0 + 5 = 5 so we put our 5. Then 7 + 0 = 7 so we put our seven.
1,875
<u> +37,500</u>
75
Then 8 + 5 = 13 so we put our three and carry our one.
1
1,875
<u> +37,500</u>
375
Then 1 + 7 + 1 = 9 so we put our 9. And finally drop down the 3
1,875
<u> +37,500</u>
39,375
ALL DONE! Our answer is 39,375
Its always good to check with a calculator to make sure you are correct.
