we have

7 3/4 + 1 5/6​

step 1

Convert mixed number to an improper fraction

7 3/4=7+3/4=31/4

Remember taht

If you multiply 31/4 by (1.5/1.5) you obtain an equivalent fraction

so

(31/4)(1.5/1.5)=46.5/6

multiply by 10/10

465/60

1 5/6=1+5/6=11/6

multiply by 10/10

(11/6)(10/10)=110/60

step 2

Adds the fractions

465/60+110/60=575/60

simplify

Convert to mixed number

575/60=540/60+35/60=9+35/60

simplify the fraction 35/60

35/60=7/12

so

we have

9+7/12=9 7/12

the answer is 9 7/12
