Arnold is solving this multiplication problem: 8.12 × 4.7.
Which of these estimates can Arnold use to help him determine
where the decimal point belongs in the product?
(A) 80 × 40 = 3,200
(B) 8 × 5 = 40
(C) 800 × 4 = 3,200
(D) 800 × 5 = 4,000
Answer:
(D) 800 × 5 = 4,000,
Explanation:
Arnold is solving this multiplication problem: 8.12 × 4.7.
So the estimates can Arnold use to help him determine
where the decimal point belongs in the product is as
8.12 has 2 decimal places value 12 so the nearest estimate of 812 is 800,
4.7 has 1 decimal place value 7 so the nearest estimate of 4.7 is 5,
therefore the total nearest estimate is 800 X 5 = 4,000 which matches with (D).

(D) 0.55 × 0.444
Answer:
(D) 0.55 × 0.444,
Explanation:
Multiplication problem will not give the same product as 5.5 × 4.44 is
5.5 has 1 decimal place value 5 and 4.44 has 2 decimal places value 44,
so the total decimal place values are 3,
Let’s check with (A) 5.5 X 4.44 which has total 3 place values,
Now with (B) 0.55 × 44.4 which has total 3 place values,
Now with (C) 55 × 0.444 which has total 3 place values,
Now with (D) 0.55 × 0.444 which has total 4 place values,
therefore, Answer is (D) will not give the same product as 5.5 × 4.44.
