Answer:
<h3>The estimate would be 3-0= nothing, so her answer is not reasonable.</h3>Step-by-step explanation:
Given the expression written by Elizabeth as 3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.
Converting 3.3 and 0.21 to fraction
3.3 = 33/10
0.21 = 21/100
Taking the difference of both fractions
Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). <u>This large difference makes Elizabeth answer unreasonable.</u>
