Question

4/7 x 1/2 in simplest form

Answer 1

4/7 * 1/2= 4/14 YOU CAN NOT PUT IT IN SIMPLEST  FORM BECAUSE THERE'S NO MULTIPLE FOR 14 OR 4

Answer 2

The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!
