Diego has run 4/5 of a race distance. He has run 7 2/3 ​

Your question is incomplete, but I am guessing that it reads something like:

“Diego has run 4/5 of a race distance. He has run 7 2/3 miles. How long is the race? Or “how many miles does he have left?”

How long is the race? = 9 7/12 miles

4/5x = 7 2/3
4/5x = 23/3
x = 23/3 • 5/4
x = 115/12
x = 9.58333
x = 9 7/12 miles

How many miles does he have left? = 1 1/12 miles

1/5 • 115/12 = 115/60 = 1.916666
= 1 55/60 = 1 11/12 miles

Let me know if I didn’t guess your question correctly and I will try to help more.

I’m pretty sure the * means multiplication. so, if you multiply 5*1, it would equal 5. they are basically are-writing 5x1 as 5*1. so they would be… 5 10152025303540455055

The right answer is option d.
