Answer:
Laura and Rob are correct
Step-by-step explanation:
we have
39/50
1) Rob said he could divide the numerator by the denominator
so
using a calculator
39/50=0.78
Rob is correct
2) Laura said she could write an equivalent fraction with 100 as the denominator to converted into a decimal

(39/50)*(2/2)=78/100=0.78
Laura is correct
