Correct. :-)
To solve the arithmetic problem: 15 - 7 2/5, we can follow a step-by-step process.
Step 1: Convert the mixed number, 7 2/5, into an improper fraction. To do this, we multiply the whole number (7) by the denominator (5) and add the numerator (2) to the result. This gives us: (7 * 5) + 2 = 35 + 2 = 37.
So, the mixed number 7 2/5 is equal to the improper fraction 37/5.
Step 2: Perform the subtraction. To subtract fractions, the denominators should be the same. In this case, the denominators are already the same, which is 5.
Now, subtract the numerators: 15 - 37/5.
To subtract fractions, keep the common denominator and subtract the numerators. In this case, the numerator of the first fraction is 15 * 5 = 75.
So, 15 - 37/5 = (75/5) - (37/5) = (75 - 37)/5 = 38/5.
Step 3: Simplify the fraction, if possible. 38/5 cannot be simplified any further as both 38 and 5 have no common factors other than 1.
Therefore, the final answer to the problem 15 - 7 2/5 is 38/5.
