Question

Jackie wants to plant 2 1/2 rows of corn in her garden. She needs 3 1/4 ounces of seed for each row. How many totally ounces of seed should Jackie buy?

Answer 1

`8(1)/(8)` ounces.

Explanation:

Given

Number of rows of corn
`=2(1)/(2)` rows.

Seed required in each row is
`=3(1)/(4)` ounces.

So, total seed required to plant corn in
`2(1)/(2)` rows is

Number of rows of corn
`*` Seed required in each row

`=(2(1)/(2))*(3(1)/(4))\\\\\ Multply\ denominator\ to\ whole\ number\ part\ then\ add\ that\ number\ to\ numerator\\\\=(5)/(2)*(13)/(4)\\ \\Divide\ 65\ by\ 8\ we\ have\ 8\ with\ reminder\ 1\\\\=(65)/(8)\\\\So,(65)/(8) =8(1)/(8)`
