Work Step by Step

1.Convert mix numbers to improper fractions. 7$\frac{3}{20}$ + 2$\frac{13}{15}$ = $\frac{143}{20}$ + $\frac{43}{15}$ 2.Convert the improper fractions into equivalent fractions using the LCD as the denominator. $\frac{143*3}{20*3}$ + $\frac{43*4}{15*4}$ = $\frac{429}{60}$ + $\frac{172}{60}$ 3.Add the numerators. $\frac{429}{60}$ + $\frac{172}{60}$ = $\frac{601}{60}$ = 10$\frac{1}{60}$
