Add and Subtract Mixed Numbers: example 4.93

Subtract: $4 \frac{3}{4} - 2 \frac{7}{8} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
Since the denominators of the fractions are different, we will rewrite them as equivalent fractions with the LCD $8 .$ Once in that form, we will subtract. But we will need to borrow $1$ first.

We were given mixed numbers, so we leave the answer as a mixed number.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.
