Giovanna used the calculations below to determine the height of a stack of 7 books that are each 2 and StartFraction 5 over 8 En
igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

  • 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

  • 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

  • 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

  • 14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8
