Question

tia rides her bicycle 9 miles a day for 6 days. which number sentence can be used to find how many miles tia rides in all? a 9 + 6 = \square b 9 × 6 = \square c 9 - 6 = \square d 9 ÷ 6 = \square

Explanation:

Step1: Understand the problem

Tia rides 9 miles each day, and this happens for 6 days. We need to find the total miles, which is the same as 6 groups of 9 miles.

Step2: Identify the operation

When we have a number of equal groups (6 days, each with 9 miles), we use multiplication. So the operation is \( 9\times6 \).

Step3: Evaluate the options

• Option A: \( 9 + 6 \) is adding the number of miles per day and the number of days, which doesn't make sense for total miles.
• Option B: \( 9\times6 \) is multiplying the miles per day by the number of days, which gives the total miles.
• Option C: \( 9 - 6 \) is subtracting the number of days from the miles per day, which is not relevant.
• Option D: \( 9\div6 \) is dividing the miles per day by the number of days, which is not relevant.

Answer:

B. \( 9\times6=\square \)
