Maria mike and Pattie are writing a report together Maria has written 1/10 of the report mike has written 1/4 and Pattie has written 1/8 use numbers line or benchmark fractions to estimate if they have more or less than 1/2 of their report left to write do they have more or less to write
To estimate if Maria, Mike, and Pattie have more or less than 1/2 of their report left to write, we can add up the fractions they have already written.
Maria has written 1/10
Mike has written 1/4
Pattie has written 1/8
Converting all fractions to have a common denominator (40), we have:
Maria: 4/40
Mike: 10/40
Pattie: 5/40
Adding these fractions together, we have:
4/40 + 10/40 + 5/40 = 19/40
Since 19/40 is less than 1/2 (which is equivalent to 20/40), Maria, Mike, and Pattie have less than half of their report left to write.
