Question

How do you turn 7 8/11 into a decimal?

Answer 1

I assume you mean 7 and 8 11ths.

You do 7x11, which is 77 and add it to 8, which is 85. you can then just plus in 85/11 into your calculator, 

OR

do 7/11 which is .7272 and add 7 which equals 7.7272

Answer 2

Convert the fractional part to a decimal, then add the result to the whole number part.
