To convert the mixed number 105:15-4 into an improper fraction, you can follow these steps:

Step 1: Convert the whole number and the fraction part to improper fractions. Step 2: Add the results from Step 1 together.

Step 1:

• The whole number is 105, which can be written as 105/1.
• The fraction is 4/18. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2 in this case. So, 4/18 simplifies to 2/9.

Step 2: Now, we add the results: 105/1 + 2/9

To add fractions, we need to find a common denominator. The least common multiple (LCM) of 1 and 9 is 9.

Now, we convert both fractions to have a denominator of 9: (105 * 9)/1 + (2 * 1)/9 945/1 + 2/9

Now, we have a common denominator, so we can add the fractions: (945 + 2)/9 = 947/9

Therefore, the improper fraction equivalent to 105:15-4 is 947/9.
