1Step 1. Given.

The statement “715-215.”

2Step 2. Concept.

When two or more fractions with the same denominators are added or subtracted then only numerators are added or subtracted, the denominator remains unchanged.

3Step 3. Calculation.

Consider the provided statement “715-215.”

 

Recall that when two fractions having the same denominator are subtracted then only numerators are subtracted, the denominator remains unchanged.

715-215=7-215

715-215=515

4Step 4. Recheck.

Now, 5 can be written as the product of 5 and 1.

15  can be written as the product of 5 and 3.

So, 515 can be further simplified as,

515=5×15×3

Striking off the common terms, we get,

515=13 

Hence, the simplified form of 715-215 is 13.
