Question

to find the product 3 3/8 * 4 1/9.tara rewrote 3 3/8 as 17/8 amd 4 1/9 as 13/9. she multiplies the fractions to find the product 221/72. what error did she make

Answer 1

The error Tara made is she rewrote incorrectly 3 3/8 as 17/8 and 4 1/9 as 13/9,

the corrected number can be rewrote as 3 3/8 as 27/8 and 4 1/9 as 37/9.

Explanation:

To find the Product of:

`3(3)/(8)* 4(1)/(9)`

The Number can be rewrote as,

`(3*8+3)/(8)* (4*9+1)/(9)\\\\(24+3)/(8)* (36+1)/(9)\\\\(27)/(8)* (37)/(9)`

Tara made error here she rewrote the number incorrectly 3 3/8 as 17/8 amd 4 1/9 as 13/9.

Now multiplying the fraction we get

`(999)/(72)`

Because she rewrote incorrectly which led her answer to multiplication of fraction, the product too was incorrect which she wrote as 221/72.
