Mixed Fraction **Subtraction** - kinda rolls off the tongue, doesn't it?

OK - how about...?

** 4**

**5 ---**

** 7**

**subtract**

** 5**

**4 ---**

** 7**

We know the**4 and 5/7** is smaller than the **5 and 4/7.**

Some might suggest converting both fractions to improper fractions...

However, if you are not particularly strong at multiplication, you might try this method...

** 4**

**5 ---**

** 7**

**First off - let's just make the 5 one LESS.**

**Why?**

**1) Because we can.**

**2) You always come away with LESS money when you go shopping. (Yes, yes, yadda, yadda, you might end up shopping for lottery tickets and win. Heard that one. Heard 'em all.)**

**So now our fraction is modified a bit from**

** 4**

**5 ---**

** 7**

To...

** 4**

**4 ---**

** 7**

But not for long. Now let's buy a top.

Hmm, stylish. Who said I had no taste?

OK. Now remember...our top (denominator) was 4.

Better now**add** some pants to this stylish ensemble.

Let's**add** the

bottom (pants) to the

top. Can this ensemble get any more stylish? I doubt it.

**4 add**** ****7** = **11**

**Remember...**

** 4**

**5 ---**

** 7**

changed to...

** 4**

**4 ---**

** 7**

**and we are now going to add the pants (bottom) onto the top**

**4 add**** ****7** = **11**

** ****11**

**4 ---**

** 7**

Now we can finish the question.

** 11**

**4 ---**

** 7**

**subtract**

** 5**

**4 ---**

** 7**

**Let's get rid of those whole numbers...**

**4 - 4 = 0**

**Now...**

**11/7 - 5/7 = 6/7**

**6/7 is our answer. Work SMART, not HARD!**

OK - how about...?

We know the

But how to **subtract** **5/7** from **4/7**?

Some might suggest converting both fractions to improper fractions...

...and coming up with **39/7** - **33/7**

...and arriving at **6/7**.

However, if you are not particularly strong at multiplication, you might try this method...

Let's go shopping...

But not for long. Now let's buy a top.

Hmm, stylish. Who said I had no taste?

OK. Now remember...our top (denominator) was 4.

Better now

Let's

And it makes sense. Why

Why not twist or rearrange things to our advantage?

It may not be easy to add 97 and 64 mentally. However, one small adjustment

such as rewriting the problem as 97 + 3 + 61 can help us to get an answer quickly

97 + 3 + 61 = 100 + 61 = 161

It is not easy to do any of these additions mentally.

25 + 27 25 + 18 27 + 18

However, if we take 2 from 27 and add that to 18, the problem becomes

25 + 25 + 20 and this is very easy to do mentally since 25 + 25 = 50 and 50 + 20 = 70
