PROBLEM

338÷214=3 \frac{3}{8} \div 2 \frac{1}{4}=

STEP 1

What is this asking?
We're asked to divide two mixed numbers, which means figuring out how many times one "fits" into the other.
Watch out!
Don't forget to convert the mixed numbers to improper fractions before dividing!

STEP 2

1. Convert to Improper Fractions
2. Divide the Fractions
3. Simplify the Result

STEP 3

Alright, let's kick things off by turning these mixed numbers into improper fractions!
Remember, a mixed number is just a whole number plus a fraction hanging out together.
We've got 3383 \frac{3}{8} and 2142 \frac{1}{4}.

STEP 4

For 3383 \frac{3}{8}, we multiply the whole number (33) by the denominator (88), which gives us 38=243 \cdot 8 = 24.
Then, we add the numerator (33) to this result: 24+3=2724 + 3 = 27.
This new number becomes our new numerator, and we keep the same denominator (88).
So, 3383 \frac{3}{8} becomes 278\frac{27}{8}.

STEP 5

Now, let's do the same for 2142 \frac{1}{4}.
Multiply the whole number (22) by the denominator (44): 24=82 \cdot 4 = 8.
Add the numerator (11): 8+1=98 + 1 = 9.
Keep the same denominator (44).
So, 2142 \frac{1}{4} becomes 94\frac{9}{4}.

STEP 6

Now, we're dividing 278\frac{27}{8} by 94\frac{9}{4}.
Remember, dividing by a fraction is the same as multiplying by its reciprocal.
The reciprocal of 94\frac{9}{4} is 49\frac{4}{9} (just flip it!).

STEP 7

So, our division problem becomes: 278÷94=27849\frac{27}{8} \div \frac{9}{4} = \frac{27}{8} \cdot \frac{4}{9}.

STEP 8

Let’s multiply those fractions!
Multiply the numerators together: 274=10827 \cdot 4 = 108.
Multiply the denominators together: 89=728 \cdot 9 = 72.
So, we have 10872\frac{108}{72}.

STEP 9

We can simplify 10872\frac{108}{72} by finding the greatest common divisor (GCD) of 108108 and 7272.
Turns out, their GCD is 3636.

STEP 10

Now, we divide both the numerator and the denominator by 3636: 10836=3\frac{108}{36} = 3 and 7236=2\frac{72}{36} = 2.
This gives us the simplified fraction 32\frac{3}{2}.

STEP 11

We can write 32\frac{3}{2} as a mixed number. 22 goes into 33 one time with a remainder of 11.
So, 32\frac{3}{2} is the same as 1121 \frac{1}{2}.

SOLUTION

Our final answer is 1121 \frac{1}{2}.
