Make an equivalent fraction 4/3= /21

Step-by-step explanation:

Step-by-step explanation:

 4          7          28

  x     =    <===

3            7          21

u can find equivalent fractions by multiplying the numerator and denominator by the same number

4/3 * 2/2 = 8/6...this would be equivalent

4/3 * 3/3 = 12/9so is this

I could go on, but I think u get it

another way this could be done is proportionsbecause they are nothing but equivalent fractions

4 / 3 = x / 21cross multiply and solve for x

(3)(x) = (4)(21)

3x = 84

x = 84/3

x = 28 <===

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
