The percentage error in the calculation is 64%.

Step-by-step explanation:

Since we have given that

A student was asked to multiply a number by 5/3.he multiple it by 3/5 instead.

Let the number be 'x'.

According to question, we get that

$\dfrac{5}{3}x-\dfrac{3}{5}x\\\\=\dfrac{25x-9x}{15}\\\\=\dfrac{16x}{15}$

So, the percentage error would be

$\dfrac{16x\times 3}{15\times 5x}\times 100\\\\=\dfrac{16}{25}\times 100\\\\=16\times 4\\\\=64\%$

Hence, the percentage error in the calculation is 64%.
