To find the product 3/7 x 4/9 Cameron simplified 3/7 to 1/7 and then mulitiplied the fractions 1/7 and 4/9 to find the product 4/63,what is Cameron's error?

Respuesta :

he was not supposed to simplify. He could have multiplied straight across and got 12/63 and he would simplify that which would be 4/21 im thinking
multiply 3/7 times 4:9 multiply
