A factory produces 305 bottles per day.

For how many days does the factory need to work in order to produce 2135 bottles?

Step-by-step solution

We need to determine how many days a factory producing 305 bottles per day will take to produce 2135 bottles.

The key to solving this problem is understanding the relationship between the total desired output and the rate of production. In this case, we employ the formula to find the number of days:

  • The number of days required = Total bottles neededBottles produced per day\frac{\text{Total bottles needed}}{\text{Bottles produced per day}}.

Let's apply the formula:

Number of days required = 2135305\frac{2135}{305}.

Now, we perform the division:

2135÷305=72135 \div 305 = 7.

Therefore, the factory needs to operate for 7 days to produce 2135 bottles.

Key Points to Remember

Essential concepts to master this topic
  • Formula: Days = Total needed ÷ Rate per day
  • Calculation: 2135 ÷ 305 = 7 days exactly
  • Check: Multiply back: 7 × 305 = 2135 bottles ✓

Common Mistakes

Avoid these frequent errors
  • Multiplying instead of dividing
    Don't multiply 2135 × 305 = 651,175! This gives you total bottles if you worked for 2135 days, not the days needed. Always divide total needed by daily rate to find time required.

FAQ

Everything you need to know about this question

Why do I divide instead of multiply here?

+

Think about it logically: you want to find how many groups of 305 bottles fit into 2135 total bottles. Division tells you how many equal groups you can make!

What if the division doesn't come out evenly?

+

If you get a decimal or remainder, round up to the next whole day. You can't work a partial day to meet your exact production goal!

How can I check if my answer makes sense?

+

Multiply your answer by the daily rate: 7 days × 305 bottles/day = 2135 bottles. If it equals the target amount, you're correct!

Is there a faster way to do this division?

+

You can estimate first! Since 300 × 7 = 2100, and 2135 is close to 2100, the answer should be close to 7 days.

What if I mixed up which number goes where?

+

Remember: big number ÷ small number = days. The total bottles needed (2135) is always larger than the daily production (305).
