Omari and Daisy live on the same street as their school the street runs from east to west Omari lives 5 1/2 blocks west of the s
satela [25.4K]

Answer:

Their houses are apart by \frac{39}{4} i.e. 9\frac{3}{4}.

Step-by-step explanation:

We have that,

Omari and Daisy lives on the same street as their school.

It is given that,

Omari lives 5\frac{1}{2} = \frac{11}{2} = \frac{22}{4} blocks west of the school.

Dasiy lives 4\frac{1}{4} = \frac{17}{4} blocks east of the school.

Thus, the number of blocks by which their houses are apart = \frac{22}{4} + \frac{17}{4} = \frac{22+17}{4} = \frac{39}{4}

Hence, their houses are apart by \frac{39}{4} i.e. 9\frac{3}{4}.
