Question

Please help I don't understand this math homework

Answer 1

Answer: 30:10

10:9 and 26:7 doesn’t work because if you select 10:9 and 26:7, IXL would correct you. So 30:10 is the answer.

Answer 2

30 : 10

Explanation:

the answer is 30 : 10 because if you multiply 3 : 1 by the same number ( in this case 10) then it is an equivalent ratio.

10 : 9 doesn't work because when you divide 10 by 3 and divide 9 by 1 it is not the same answer so that is not an equivalent ratio. Same goes for 26 : 7

when you divide it by the same number it will no equal 3 : 1.
