Answer:
18 and 11/16
Step-by-step explanation:
I converted the two numbers into improper fractions which leaves me with
71/8+157/16
I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:
142/16+157/16
I can now add the 2 numbers together and I get:
299/16
now we just need to convert the number into a mixed number by dividing, and I am left with:
18 and 11/16
