Answer:
1. 285 2. 2 795 3. 26 320
Step-by-step explanation:
19
<u>x 15</u>
95
<u> 190</u>
285
To get the 95, multiply 9 x 5, which is 45. Then, carry over the 4 and multiply 1 x 5, which is 5. Add 5 + 4, which is 9, so then you have 95.
To get the 190, you first have to write a 0 in the unit's place because we are working with the tens. Then, you multiply 9 x 1, which is 9. You then multiply
1 x 1, which is 1.
For the final step, you add 95 + 190 = 285 and this is your answer.
