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.
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
To find all decimals that are equivalent to (7×100)+(5×1)+(8×1/10)+(1×1/100), we need to simplify the expression:
(7×100)+(5×1)+(8×1/10)+(1×1/100)
= 700 + 5 + 0.8 + 0.01
= 705.81
So, the decimal equivalent to (7×100)+(5×1)+(8×1/10)+(1×1/100) is 705.81.
Therefore, you can choose 705.81 as the correct answer.
To determine all the decimals that are equivalent to the expression (7×100)+(5×1)+(8×1/10)+(1×1/100), we can break down the expression step by step:
(7×100) = 700
(5×1) = 5
(8×1/10) = 0.8
(1×1/100) = 0.01
Now we can add these values together:
700 + 5 + 0.8 + 0.01 = 705.81
So, the decimal equivalent to the expression is 705.81.
Now let's analyze the other options you provided:
1. 75.081: This is not equivalent to the expression (7×100)+(5×1)+(8×1/10)+(1×1/100), as it has a different decimal part.
2. 705.810: This is equivalent to the expression, as it matches the calculated result of 705.81 after rounding.
3. 705.801: This is not equivalent to the expression, as it has a different decimal part.
4. 75.810: This is not equivalent to the expression, as it has a different integer part.
5. 705.81: This is equivalent to the expression, as it matches the calculated result of 705.81.
6. 705.081: This is not equivalent to the expression, as it has a different decimal part.
Therefore, the correct choices among the options you provided are:
- 705.810
- 705.81
