Answer 3 is B - again you can add the answers to 0.52 to try and get 0.78 in this case it’s B or 0.26
Answer 4 is D - 46.63 and 5.38, first add the 5 and 46 to get 51 then you add the 0.3 and 0.6 to get 0.9, and 0.3 added to 0.8 is 0.11. Add it all together to get 52.11
Answer 5 is C - yet again you can add the answers to the 3.30 to get 5.03 in this case it’s C or 1.73
