Answer:
2.- 100
Step-by-step explanation 1:
[tex]\frac{7}{25} + \frac{3}{4} = \frac{28}{100} + \frac{75}{100} = \frac{103}{100}[/tex]
↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.
Step-by-step explanation 2:
[tex]\frac{(7 * 4) + (3 * 25)}{4 * 25} = \frac{28 * 75}{100} = \frac{103}{100}[/tex]
↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.
