Answer 1

Answer:

145/100

Step-by-step explanation:

4/9 + 1/4 + 4/5

First step

Find the L.C.M of the denominators.

Here the denominators are 9, 4 and 5

so, L.C.M of 9, 4, and 5 is 180.

Second step

Multiply the denominators with a number so that the denominator becomes 180. Multiply the numerator with the same number.

Therefore,

{(4 × 20) / (9 × 20)} + {(1 × 45) / (4  × 45)} + {(4 × 36) / (5 × 36)}

= (80 + 45 + 144) / 180

= 269/180

= 145/100
