$⟹\frac{9}{10} + \frac{11}{15} + \frac{7}{20}$

L.C.M OF 10,15 & 20 IS 60

$⟹ \frac{9 \times 6 + 11 \times 4 + 7 \times 3}{60} = \frac{54 + 44 + 21}{60}$

$⟹ \frac{98 + 21}{60} = \frac{119}{60}$

Answer 2

Step-by-step explanation:

$\frac{9}{10} +\frac{11}{15}+\frac{7}{20}$

First, we make the denominator the same. For that, we take the LCM of the denominators.

LCM of 10,15,20 is 60. This means that 60 is the least number divisible by 10,15,20

Now,

60/10 = 6

So we multiply 6 in both numerator and denominator in $\frac{9}{10}$

Similarly, we do the other ones.

$\frac{9 *6}{10*6} +\frac{11*4}{15*4} +\frac{7*3}{20*3} = \frac{54}{60} +\frac{44}{60} +\frac{21}{60} =\frac{119}{60} =1\frac{59}{60}$

Answer is $1\frac{59}{60}$
