220:43

Do you mean the ratio 220:43 or the division 220 ÷ 43?

Here are quick notes for both:

• Simplest form (ratio): gcd(220, 43) = 1, so 220:43 is already in lowest terms.
• If you meant the division: 220 ÷ 43 ≈ 5.11628. As a mixed number, 5 with remainder 5, i.e. 5 and 5/43.
• Decimal approximate: 5.116279...

Extra useful tip in ratio problems:

• If you know A:B = 220:43 and you also know A+B = N, then A = 220N/263 and B = 43N/263. You’ll get integers only when N is a multiple of 263.

If you share the exact context or what you’re trying to find, I can tailor the solution.
