Question

Drag the cards to create a number that matches these rules.

The number ends in the tenths place.
20 is the nearest ten when rounding numbers(4,1,6)

Answer 1

Explanation:

To create a number that matches the given rules, we need to find a number that ends in the tenths place and is rounded to 20 when rounding to the nearest ten.

Let's break this down step-by-step:

1. The number ends in the tenths place: This means that the number should have a digit in the tenths place, which is one place to the right of the decimal point. For example, 3.1 or 5.6.

2. 20 is the nearest ten when rounding numbers (4, 1, 6): To determine if a number rounds to 20 when rounded to the nearest ten, we need to look at the digit in the ones place. If the digit is 4 or less, we round down. If the digit is 5 or greater, we round up.

For example:

- If we have the number 15.6, the digit in the ones place is 5, so when rounded to the nearest ten, it becomes 20.

- If we have the number 13.4, the digit in the ones place is 4, so when rounded to the nearest ten, it becomes 10.

Based on these rules, we can create multiple numbers that match the given criteria. Here are a few examples:

- 23.6: The digit in the tenths place is 6, which means when rounding to the nearest ten, it becomes 20.

- 18.1: The digit in the tenths place is 1, which means when rounding to the nearest ten, it becomes 20.

- 12.6: The digit in the tenths place is 6, which means when rounding to the nearest ten, it becomes 20.

Remember, there are multiple numbers that can meet these criteria. The examples provided are just a few possibilities.

Answer 2

The number 16.4, created using the digits 4, 1, and 6, ends in the tenths place and rounds to 20 when rounding to the nearest ten.

How to find nearest ten?

To find a number that ends in the tenths place and rounds to 20 when using the digits 4, 1, and 6, we need to consider a few key points:

Rounding to the nearest ten means any number from 15 (inclusive) to 24.99 (exclusive) will round to 20.

The number must end in the tenths place, which means it should have one digit after the decimal point.

Create all possible numbers with these digits and check which ones round to 20:

14.6

16.4

41.6

46.1

61.4

64.1

Now, see which of these numbers will round to 20:

• 14.6 rounds down to 10 (not suitable).
• 16.4 rounds up to 20 (suitable).
• 41.6 rounds up to 40 (not suitable).
• 46.1 rounds up to 50 (not suitable).
• 61.4 rounds up to 60 (not suitable).
• 64.1 rounds up to 70 (not suitable).

So, out of these combinations, only 16.4 satisfies the conditions: it ends in the tenths place and rounds to 20 when rounded to the nearest ten.
