What is 21 divided by 1/3?

Answers

Answer 1

Answer:

21 divided by 1/3 is equal to 63.

Given that we need to divide 21 by 1/3,

To divide a number by a fraction, you can multiply the number by the reciprocal of the fraction.

The reciprocal of a fraction is obtained by swapping the numerator and the denominator.

In this case, you want to divide 21 by 1/3. To find the result, you multiply 21 by the reciprocal of 1/3. The reciprocal of 1/3 is 3/1, which means you swap the numerator and the denominator to get 3/1.

So, the division problem can be rewritten as 21 multiplied by 3/1:

21 x (3/1)

Now, you can simplify the expression by multiplying the numerators (21 x 3) and the denominators (1 x 1):

63/1

Since the denominator is 1, you can write the result as: 63

Therefore, 21 divided by 1/3 is equal to 63.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The Henry family drove 276.5 miles on the family vacation.

And, They used 7.9 gallons of gas.

Now,

Since, In 7.9 gallons of gas distance cover by the Henry family = 276.5

Hence, In 1 gallons of gas distance cover by the Henry family = 276.5/7.9

= 276.5 / 7.9

= 35 miles

Thus, There are 35 miles per gallon of gas get on the trip.

To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.
