How can i Multiply. * 2/7*3/5

You first line them up and you wanna find the lcd and then remember what you do to the bottom you do to the top so

2/7 times 2 by 5 and times 7 by 5 also then that would equal 10/35

then you times 3 by 7 and times 5 by 7 to get 21/35 then add 10 and 21 to get 31 then it will be 31/35 then try to reduce it but u cant so the answer is 31/35
