Answer:

28

Step-by-step explanation:

according to your picture its a negative times a negative which is going to give you a positive so that leaves two I also know that 14*2 is 28 but you still need to do the fraction which is 9/90or 9/10 so the best estimate is 28

Sorry if that doesn't make since i hope it helps
