Marcia said that if she estimates 73 x7, the product will be less than the exact answer. Is she correct? Explain.
I think:
it depends. If you round 73 and 7 then the estimate will be larger than the actual value(70*10=700 is larger than 73*7=511) if you on round 70 than the estimate will be smaller (70*7=490).
521
what is this stipid answer
i am in 3erdgr I cant find the answer! can some on help the problem is: Marcia said that if she estimates 73 times 7 the product will be less than the exact answer. is she correct? Explain. ps you round the 73!
How do we do this
To determine whether Marcia is correct or not, we first need to estimate the exact answer to the multiplication problem and then compare it to 73 x 7.
To estimate the exact answer, we can start by rounding both numbers to the nearest ten.
73 rounded to the nearest ten is 70, and 7 rounded to the nearest ten is 10.
Next, we multiply the rounded numbers to get our estimated answer: 70 x 10 = 700.
Now, we can compare our estimated answer of 700 to the actual multiplication of 73 x 7.
Calculating 73 x 7, we find that the product is 511.
Since 511 is less than 700, Marcia's statement is incorrect. The exact answer to 73 x 7 is not less than her estimate; it is actually greater.
