The two fractions that you gave are equivalent... 12 is a common denominator. you have to multiply 3 × 4 to get 12. so if you multiply the same number by the numerator 2× 4 = 8.

2/3 × 4/4 = 8/12

The reason they are equivalent when you multiply by 4/4 is because you are just multiplying by 1 (4/4 = 1). 1 times anything is itself. So the way it looks changes but the value stays the same.

The fraction 8/12 and 2/3 are equivalent on because they are equivalent because you just have to multiply 12 * 2 wishes 24 and 8 * 3 wishes 24 then with them was 3/4 and 20 / 28 walk just have to multiply 4 * 20 and 28 * 3 which 20 * 4 is 80 and 3 * 28 is 84 so no those are not equivalent now 4/5 and 12/16 are not equivalent because 16 * 4 =64 + 5 * 12 + 60 so no they are not equivalent now 7/10 and 21/30 are equivalent because 7 * 30 is 210 and 10 * 21 is 210 times so those are the answers and yes

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.
