There is no number to multiply 89 with to get the answer 830 and here's the explanation...
Step-by-step explanation:
You see, when you multiply:
89 x 9 = 801
When you multiply with a higher number like 10 to get closer to 830, it equals to a different number which is greater than 830:
89 x 10 = 830
Therefore, there is no number to multiply with 89 to get the answer 830.
Side Note:
166 x 5 = 830
Hope this helps!
