Emma's grades are the following along with the weight of each assignment:

6/10 (10%)
26.5/47 (20%)
22.5/50. (20%)
Hw worth (10%) not yet added
Final worth (40%) not yet added.

What is her current grade before the hw and final?

so so far we have done 50% of the class

so multiply them all by 2
( you could leave it all as is and multiply by 2 at the end)

.6*.2 + (26.5/47 )*.4 + (22.5/50)*.4

= .12 + .226 + .18

= .526 or 52.6 out of 100
