Robins 15 18 27 30 cardinals 5 6 9 10 what’s the proportionality ratio of robins to cardinals

3:1

Step-by-step explanation:

The Robins' numbers are 3 times the cardinal's numbers, so therefore when simplified, the ratio is 3 to 1, 3:1, or 3/1.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
