First, invert (get the reciprocal of ) 7/2 to get 2/7. Then multiply 43/5 times 2/7.
With the multiplication of fractions, you multiply all of the numerator number and multiply all the denominator numbers.
so multiply 43 times 2 for the numerator, = 86
multiply 5 times 7 for the denominator, = 35
so you get 86/35. They will want the answer in mixed number format, because that's the form the original numbers were in. So you should convert 86/35 to 2 and 16/35.
