At the beach, denise and her sister both built sandcastles and then measured their heights. Denise's sandcastle was 1 7/12 feet tall and her sister's was 5/12 of a foot tall. How much taller was denise's sandcastle than her sister's? In mixed number

Respuesta :

Answer: [tex]1 \frac{2}{12}\ ft[/tex]

Step-by-step explanation:

The height of Denise castle is  [tex]1 \frac{7}{12}=\frac{12\times 1+7}{12}=\frac{19}{12}\ ft[/tex]

height of her sister  [tex]\frac{5}{12}\ ft[/tex]

Difference between the height of the castle

[tex]\Rightarrow \frac{19}{12}-\frac{5}{12}=\frac{14}{12}[/tex]

In mixed fraction it is [tex]\frac{14}{12}\ or\ 1 \frac{2}{12}\ ft[/tex]
