    After you multiply by 75, you get: \[{4 \over 5}(75)=x \]

    You should simplify it actually, your answer should be x=(75/5)(4)=15*4 --> x=60. So your final answer is x=60

    Let me rewrite it: \[{7 \over 8}={56 \over n}\] Now multiply the top of the left side by the bottom of the right side, and the top of the right side by the bottom of the left side.

    So you multiply 7 by n and 56 by 8, you then get: 7n=56*8 But as you said 56*8=448. So the answer would be: 7n=448
