Question

Which of the expressions below has a 1 in the tenths place of the product? Select all that apply. A) 18.3 x 7 B) 6.5 x 4.31 C) 8.54 x 2.3 D) 5.4 x 2.8

Answer 1

Expressions A (18.3 x 7) and D (5.4 x 2.8) are the ones with a 1 in the tenths place of the product after performing the multiplication, resulting in the products 128.1 and 15.12 respectively.

Step-by-step explanation:

The question asks which of the given expressions will have a 1 in the tenths place after performing the multiplication. We need to multiply each pair of numbers and check the tenths place in the product.

18.3 x 7: Multiplying these numbers gives us 128.1. So, there is a 1 in the tenths place.

6.5 x 4.31: The product is 28.015. There is no 1 in the tenths place, it is in the hundredths place.

8.54 x 2.3: The product is 19.642. There is no 1 in the tenths place; instead, it's in the ones place.

5.4 x 2.8: Multiplying these numbers results in 15.12. Here, we see a 1 in the tenths place.

Hence, expressions A and D have a 1 in the tenths place of the product.

Answer 2

Answer: A) 18.3 x 7 and D) 5.4 x 2.8

Step-by-step explanation:

A) 18.3 x 7 = 128.10

We can infer that 1 is in the tenths place.

B) 6.5 x 4.31 = 28.015

We can infer that 1 is not in the tenths place but rather the hundredths place.

C) 8.54 x 2.3 = 19.642

We can infer that 1 is not in the tenths place.

D) 5.4 x 2.8 = 15.12

We can infer that 1 is in the tenths place.
