Is dividing by the same as multiplying by?

The purpose of this task is to help students understand that when we divide by a fraction, it is the same as multiplying by its reciprocal. By carrying out this work outside of a context, students can focus on numbers and operations.

Why is dividing by 0.5 the same as multiplying by 2?

Why is dividing by 1/6 the same as multiplying by 6?

Each person gets one piece, so each person gets 14 of a pizza. Dividing a fraction by a whole number is the same as multiplying by the reciprocal, so you can always use multiplication of fractions to solve division problems.

What is the difference between dividing and multiplying by 1/5?

Extended answer: dividing a number X by 1/5 is looking at how many times 0.2 is in X. Multiplying a number X by 5 is adding X up 5 times. Let’s take a random number, let’s make it 3. 3 : 0.2 = 15 (for those of you that don’t know, 1/5 and 0.2 are the same thing), 0.2 appears 15 times in 3. This will work for any value of X. Why?

Is n divided by 1/5 the same as n times 5?

Depends on what you mean by “same”. If you mean numerically equivalent, then yes. n divided by 1/5 is exactly equal to n times 5. They both yield the same number. But do the two phrases mean the same thing? Not really.

Is dividing by its opposite the same as multiplying by it?

Same answer, different questions. when you divide anything by a number you actually multiply the number by its reciprocal. Yes, as dividing by a fraction is the same as multiplying by it’s opposite. Here 1/5 wich’s opposite is 5/1 wich is the same as 5.

Is it possible to write 1/5 as a fraction?

Yes. For any number n, if you take 5n = n/ (1/5), then you can write the fraction 1/5 as 5^ (-1). When you take 5n=n/ [5^ (-1)], then that is the same as 5n = n * 5, which means that 5n=5n. Of course it is right. There are ten of those in a euro. If you were asked to divide a single euro into these you would end up with ten such coins.
