Work Step by Step

If we want to add fractions, we have to find a common denominator. Here, this can be 100. This is not the lowest common denominator, but it is the multple of both 10 and 25, and it is easy to calculate with. $\frac{9}{10}+\frac{16}{25}=\frac{10\times9}{10\times10}+\frac{4\times16}{4\times25}=\frac{90}{100}+\frac{64}{100}=\frac{154}{100}=\frac{77}{50}=1.54$
