B. about 20

Explanation:

To estimate the quotient 117.83 ÷ 5.67 using compatible numbers, we can round the dividend (117.83) and the divisor (5.67) to numbers that are easier to work with.

Rounding 117.83 to 120 and 5.67 to 6, we get:

120 ÷ 6 = 20

So, the estimated quotient is about 20.

To estimate 117.83 ÷ 5.67 using compatible numbers, round the dividend and divisor to values that are easier to divide.

- **117.83** is close to **120** (a multiple of 6).
- **5.67** is closer to **6** (only 0.33 away) than to 5.

Using these compatible numbers:
**120 ÷ 6 = 20**, which aligns with option **B**. Checking exact values confirms the estimate is reasonable (actual quotient ≈ 20.78).

117.83 can be rounded to 120 and 5.67 can be rounded to 6. 120÷6=20.
B
minimax To estimate the quotient of 117.83 ÷ 5.67 using compatible numbers, we should round the numbers to make them easier to divide while keeping the result close to the actual quotient.

117.83 can be rounded to 120, ***patible numbers that are easier to work with are 120 and 6.

Now, we can estimate the division:

120 ÷ 6 = 20

So, the estimated quotient is about 20.

Answer: B. about 20

kimi To estimate the quotient of 117.83 ÷ 5.67, we can round the numbers to make the division easier:

117.83 is close to 120 (rounding to the nearest ten).
5.67 is close to 6 (rounding to the nearest whole number).

Now, let's divide the rounded numbers:

120 ÷ 6 = 20

So the estimated quotient is about 20.

Explanation:
To estimate the quotient 117.83 ÷ 5.67 using compatible numbers, we can round the numbers to make the division easier.
Round 117.83 to the nearest ten, which is 120.
Round 5.67 to the nearest whole number, which is 6.
Now, divide the rounded numbers: 120 ÷ 6 = 20.
So, the estimated quotient is about 20.

zhipu To estimate the quotient \( 117.83 \div 5.67 \) using compatible numbers, we should round each number to a value that makes the division simpler.

- \( 117.83 \) is close to \( 120 \).
- \( 5.67 \) is close to \( 6 \).

Now, we can estimate the quotient:

\[ 120 \div 6 = 20 \]

So, the best estimate is:

B. about 20
