1 5/7

Explanation:

When I was taught to solve fractions, I used "Cross Multiplication." How to use cross multiplication is to multiply the first numerator with the second denominator, and the first denominator with the second numerator. To make it easier, if the question was this, x/y = a/b you'd have ya and xb. So what you do with those numbers is make them equal. Let's put in your problem. 7/3 = 4/t If you cross multiply, you get 7t and 12. To get t, you make them equal. If you divide both sides by 7, you get t and 12/7. 12/7 is also 1 5/7, making the answer 1 5/7.
