How do i solve this i am really confused

You have to move the decimal place of the first factor to the left two places. So, for the first question, it would be .47. Then you just multiply it by the other number. So, the answer for the first question would be the product of .47 and 70.

So u put 65 and then 100 under it like a fraction the. U put a on top of 152 as a fraction then u cross multiply which gives I 100a and 9880 after this u just divide by l
100 to get the variable by itself and your answer should be 98.8
