I've attached the answer key for Workbook Unit 5 Lesson 2 from last week.

The next section moves from fractions into decimals.  There's two assignments that you can try to get an understanding of how fractions are related to decimals.

Textbook Unit 5 Lesson 4  Page 178 #1-11

Workbook Unit 5 Lesson 4  Page 72

If you can't figure out some of the questions don't get stressed out about them.  Try to do the questions that you can, that's all you can ask for.

Good luck with them.

Stay safe Grade 5 and enjoy the nice weather!
