4:3 19:11 equivalent ratios?

No

Step-by-step explanation:

We can tell if these ratios are equivalent by dividing the numerators and denominators. If we end up with the same result, these ratios are equivalent.

These two numbers are not equivalent, so these ratios aren't equivalent to each other

Hope this helped!

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
