Full process​

Answer 1

Answer:

-87/20

First find the LCM of all 3 denominators (120 is the LCM)

Then, make all denominators 120 by multiplying them with the number which when multiplied by the denominator gives 120 (For eg, 8 must be multiplied by 15 to get 120)

Then, multiply the numerator with the number denominator multiplied with to become 120

So, the equation will then look like this,

45 - 100 - 32 / 120

45 - 132 / 120

-87 / 120
