Converting Expressions to Fractions

To represent the given expressions in the form of fractions, we can follow these steps:

1. Converting m/5 + 3/t to a Fraction: - The expression m/5 + 3/t can be represented as a fraction by finding a common denominator for 5 and t. - The common denominator for 5 and t is 5t. - Multiplying the first term by t/t and the second term by 5/5, we get the fraction (m*t + 15)/(5t).

2. Converting 5/12a - 1/18a to a Fraction: - The expression 5/12a - 1/18a can be represented as a fraction by finding a common denominator for 12a and 18a. - The common denominator for 12a and 18a is 36a. - Multiplying the first term by 3/3 and the second term by 2/2, we get the fraction (15/36a - 2/36a).

Therefore, the expressions can be represented as fractions: - m/5 + 3/t = (m*t + 15)/(5t) - 5/12a - 1/18a = (15/36a - 2/36a)

These fractions represent the given expressions in the required form.
