She estimates the thickness of the two coins to be less than 3 millimeters. Write a symbol (, or =) in the box to make the statement true. Then use the statement to tell whether Hailey's estimate is correct. 12 + 12 + 1 Is Hailey's estimate correct?

Sagot :

A dime has a thickness of 1 7/20 mm and a penny has 1 1/2 mm.

Stacking both coins, we will have :

[tex]1\frac{1}{2}+1\frac{7}{20}[/tex]

and we have the inequality :

[tex]1\frac{1}{2}+1\frac{7}{20}\boxed{\text{ }}1\frac{1}{2}+1\frac{1}{2}[/tex]

Note that 1 7/20 is less than 1 1/2, so the inequality symbol is "<"

[tex]1\frac{1}{2}+1\frac{7}{20}<1\frac{1}{2}+1\frac{1}{2}[/tex]

since 1 1/2 + 1 1/2 is equal to 3mm

Therefore, the thickness of stacking coins is less than 3mm

Hailey's estimate is correct (Yes)
