once you time 4 by 5 it equates to 20 and also then you add the molecule which then equals 21.. Friend then obtain 21/4. (that"s just how you prove this is the exactly answer)

Hello!

This is actually a pretty easy one. By "mixed" they average in the type like "1 1/2" instead of "3/2". So it"s a "mix" of entirety numbers and also fractions.

You are watching: 21 4 as a mixed number

Here we have 21/4. To transform it to blended we first need to recognize how plenty of whole numbers us have. That"s straightforward to figure out simply divide 4 right into 21. How numerous whole times walk 4 get in 21? fine 5, since 5 x 4 = 20. It"s not 6 because 6 x 4 = 24 and that would go over 21.

So we know 4 goes right into 21 5 totality times. Exactly 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 mixed number:

5 1/4

Is that correct? us can inspect our job-related by converting ago and seeing if we obtain what we began with.

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

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

Hope the helps.

Oh the quick means to deal with this is:

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

21/4 = 5 1/4.

Hope the helps!
