Question

find the following sums and express your answer as mixed fraction helphelp plz​

Answer 1

Answer:

Step-by-step explanation:

27/20 + 15

LCM  of 20 and 15 is 60

so: 27/20 + 15 <-- multiply 27 x 3/20 x 3 and 15 x 60/1 x 60

                          cuz LCM is 60, you have to multiply the denominators by a                number so that it'll be 60, and multiply the numerators by the same number

now: 81/60 + 900/60 = 981/60

981/60 = 327/20

=> 16 and 7/20

hope it helped
