Question

Erase 3/5 of 2/3. How much of 3/3 will be shaded?

Answer 1

It looks confusing but it's .80/3 not 80% but like .8 of 3 like not 1. but .8 because 2.2 isnt being shaded.

Answer 2

how much is 3/5 of 2/3? well, it's just their product, thus

`\bf \cfrac{3}{5}\cdot \cfrac{2}{3}\implies \cfrac{3}{3}\cdot \cfrac{2}{5}\implies 1\cdot \cfrac{2}{5}\implies \cfrac{2}{5}`

now, bearing in mind that 3/3 is just 1 whole, and we can express it as 5/5 as well, so 3/5 of 2/3 of a whole is just 2/5 of the whole.
