2500mg + 3.15mg = 2503.15mg or 2.50315g

2) 1lb = 16oz

2lb = 32oz 32 burgers

3) 3ft=1yd 3yd=9ft rulers

Might q. #3 ask for #of ft. long rulers in 3 metersticks?

If so:

1m= 39in(+/-) 3m=117in

117in/12in=9.75 or closest to 10ft long rulers

4) 3.04m+4.25m=7.29m

304cm+425cm=729cm

1) 2.5g + 3.15mg = 2500mg+3.15mg=2503.15 mg

4) 3m+4cm = 300cm+4cm = 304cm

…..4m+25cm = 400cm+25cm=425cm

…..304cm + 425cm = 729cm
