when you times 4 by 5 it equates to 20 and also then you include the numerator which then equals 21.. Friend then gain 21/4. (that"s just how you prove this is the correct answer)
*

Hello!

This is in reality a pretty basic one. By "mixed" they median in the form like "1 1/2" instead of "3/2". For this reason it"s a "mix" of entirety numbers and also fractions.

You are watching: 21/4 as a mixed number

Here we have actually 21/4. To transform it to combined we very first need to recognize how countless whole numbers us have. That"s straightforward to number out simply divide 4 into 21. How plenty of whole times walk 4 go into 21? fine 5, because 5 x 4 = 20. It"s not 6 due to the fact that 6 x 4 = 24 and also that would go end 21.

So we understand 4 goes into 21 5 totality times. How much is left over? Well, 5 x 4 = 20 so there is 1 left over. One what? One 4th, or 1/4.

So we have the right to now write it as a combined number:

5 1/4

Is it correct? we can check our job-related by converting back and seeing if we acquire what we began with.

5 x 1/4 + 1/4 = 20/4 + 1/4 = 21/4

Yep, checks out - this is the exactly answer!.

Hope the helps.

Oh the quick way to settle this is:

21/4 = 21 separated by 4 = 5 remainder 1 (one what? remember, it"s 1/4ths). So also the quick way, us get:

21/4 = 5 1/4.

Hope that helps!
