An informal proof

Step-by-step explanation:

I just did this question

(It could be wrong though considering that they can be either formal or informal, it depends on the situation!)

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
