Answer: On the first one its either A or D. (I think)
Step-by-step explanation:
So what I did was I multiplied 22 and 6.32 together and got 139.04 and the closest estimate to that would be 160 because 39 is closer to 60 than 20 (A) and since its not 150 the estimate would be lower than higher. (D)
I think it's A - You can't choose D or B because the answer is more than that. - You can't choose C because it's too far from the answer. - So the answer is A because it's the nearest to the answer.
