Question
i need help with writing 2 equivalent ratios for 7:4 and writing 36:45 and 22:25 in simplest form


Answer
to write two equivalent ratios, just multiply 7 and 4 by any two numbers.  2 and 3 are easiest, so
7:4 = 14:8 = 21:12  To reduce, just treat the ratios as a fraction and reduce them like you would a fraction.  What is the highest common multiple of each number.  For 36:45 it's going to be nine and for 22:25, there is no common factor, so it IS in the simplest form.

36:45 = 4:5
