Answer:
(0.25)⋅(0.044) = 0.011
Step-by-step explanation:
Two students have different ways to calculate (0.25)⋅(0.044) as a decimal.
Show, in detail, how each student might compute this product. (upload your work when complete)
We are given:
(0.25)⋅(0.044)
= 0.25 × 0.044
a) For Elena
Elena says, "I find 25⋅ 4.4 and then move the decimal point."
What Elena did was she multiplied both
number by 100
= (0.25 × 100) × (0.044 × 100)
We add up the decimal points from 0.25 and 0.044 = 5
Hence, the answer we get in step 1 is divided by 100000 in other it move the brackets
(0.25 × 100) × (0.044 × 100)/100000
= 0.011
b) For Diego
Diego says, "0.25 is the same as 1/4, so I found 1/4 of 0.044."
Diego converted 0.25 to fraction
= 0.25 × 100/100
= 25/100 = 1/4
Since, (0.25)⋅(0.044)
= 0.25 × 0.044
Then:
1/4 of 0.044
= 1/4 × 0.044
= 0.011
