7×100 = 700
5×1 = 5
8×1/10 = 8 / 10 = 0.8
1×1/100 = 1 / 100 = 0.01
(7×100)+(5×1)+(8×1/10)+(1×1/100) = 700 + 5 + 0.8 + 0.01 = 705.81
Please help me to choose all decimals that are equivalent to (7×100)+(5×1)+(8×1/10)+(1×1/100)
75.081
705.810- yes
705.801- ?
75.810
705.81- yes
705.081-?
I'm not sure enough if 705.81 and 705.081 have to be choosen too.
