Five numbers are in the ratio 1:2:3:4:5. the sum of the numbers is 90. work out thhe range of the numbers

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

1+1=22×1=22-1=11-1=1duh
