Explanation:**
**Given a zoo is planning a new building for the penguin exhibit.

First, they made a model that was 1.3 meters tall. Then,

they made a more detailed model that was 1.5 times as tall as the first model.

So the detailed model is 1.3 x 1.5 = 1.95 meters tall,

The building will be 2.5 times as tall as the height of the detailed model.

So the height of the new building was 1.95 ÷ 2.5 = 0.78 meters.

Question 18.

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,

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.

Question 20.

**Multi-Step** Gina bought 2.5 pounds of peaches that cost $1.38 per pound at the grocery store.

Amy went to the local farmer’s market and purchased 3.5 pounds of peaches at $0.98 per pound.

Who spent more money, and how much more?
