- You may flatten the middle syllable into a quick /ɪ/ or /ə/ and merge the second and third syllables; fix by easing the /i/ to a crisp /iː/ or /ɪ/ depending on dialect, then clearly open to /ɒ/ or /oʊ/ in the final syllable. - Some speakers substitute a hard /d/ or add a本站/dicents before /ɒz/; avoid adding extra consonants. Practice with minimal pairs: rat-e-ohs vs ray-she-oss to lock the /ʃ/ plus /i/ sequence. - In rapid speech, the /r/ can be weakened or skipped; maintain a focused /ˈreɪ/ onset to prevent confusion with “rates”.
"The ratios of sugar to water determine the sweetness of the solution."
"In the problem, the ratios must be simplified before you can compare them."
"We discussed the ratios of rewards to risks in the investment strategy."
You say RAT-ee-ohz, with primary stress on the first syllable. IPA: US /ˈreɪ.ʃi.ɒz/ or /ˈreɪ.ʃi.oʊz/ depending on accent; UK /ˈreɪ.ʃɪ.ɒz/; AU /ˈreɪ.ʃɪ.ɒz/. Start with a clear /reɪ/ then a crisp /ʃi/ and close with /ɒz/ or /oʊz/ in US. Keep the /t/ soft, almost blending into the /r/ onset of the second syllable.”,
Common errors: (1) Dropping the /t/ or turning it into a hard /d/ making /ˈreɪ.di.ɒz/; (2) Slurring the middle syllable so it sounds like /ˈreɪ.sɪəs/; (3) Misplacing stress or flattening into /ˈreɪ.tiː.ɒz/ in fast speech. Correction: keep a crisp /t/ or a light tap before the /i/, ensure the second syllable has a clear /i/ or /ɪ/ depending on dialect, and maintain primary stress on the first syllable /ˈreɪ/. Practice with focused repetition of /ˈreɪ.ʃi.ɒz/.”,
US: tends to /ˈreɪ.ʃi.oʊz/ with a clear /oʊ/ at the end; UK: often /ˈreɪ.ʃɒz/ or /ˈreɪ.ʃi.ɒz/ with a shorter final vowel; Australian: often /ˈreɪ.ʃɪ.ɒz/ or /ˈreɪ.ʃi.əz/ with a reduced final /əz/ in rapid speech. The middle syllable can be a full /i/ or a reduced /ɪ/ depending on tempo. Overall rhoticity is variable: US rhotic, UK less rhotic in some forms, AU typically non-rhotic in careful speech but strongly rhotic in connected speech with /r/ perceived in some contexts.”,
The difficulty lies in steering the /t/ release before a front vowel /i/ and the high-back vowel in the final syllable. The sequence /ˈreɪ.ʃi.ɒz/ requires a crisp, light /t/ with minimal tongue lift between /ʃ/ and /i/. Rapid speech may collapse to /ˈreɪ.ʃəs/ or /ˈreɪ.ɒz/ if the /i/ is elided. Practice separating the syllables briefly, then blend into a smooth, flowing rhythm to maintain the right vowel qualities and end with a clear /z/ voice.”,
A unique feature is the glide from /i/ to /ɒ/ (or /oʊ/ in some accents) between the second and third letters, which can be subtle when speaking rapidly. You should aim for a short, crisp second syllable /i/ followed by a distinct /ɒ/ or /oʊ/ in the final syllable, not a prolonged vowel. In careful speech, maintain a clean transition from /i/ to /ɒ/ so the final /z/ remains voiceless until voiced by surrounding vowels.

- US: maintain rhotic /r/ with a rounded /ɔɪ/? No. Correction: focus on durable /r/ then /eɪ/ sequence; keep final /z/ voiced but subtle in speed. - UK: less pronounced rhoticity; the second vowel may become a short /ɪ/ or /ɒ/ depending on region; ensure you don’t merge /ɒ/ into /ə/ in fast speech. - AU: tends toward a broader diphthong in /eɪ/ and often a slightly reduced final vowel; keep the /r/ non-rhotic in careful speech, but in connected speech you might hear a light /ɹ/ depending on speaker. IPA references: /ˈreɪ.ʃi.ɒz/ (US), /ˈreɪ.ʃɒz/ (UK), /ˈreɪ.ʃɪ.ɒz/ (AU).
The word ratio comes from late Latin ratio, from Latin ratiō meaning reckoning, calculation, or account. The sense of proportional relation extends from mathematical usage in Latin and medieval algebra. The English plural ratios emerged by adding -s to ratio, which itself entered English in the 14th–15th centuries via Old French ratio or Latin ratiō. Early mathematical texts borrowed ratio to describe the relationship between two quantities, often expressed as a fraction or a:b. Over time, the term broadened to include any comparative relationship or rate (e.g., “the ratios of costs to benefits”). The 17th–18th centuries saw a formalization in algebra and geometry where ratios and proportions became foundational tools in teaching proportional reasoning. By the 19th and 20th centuries, ratio expanded into statistics and data analysis, used for odds, probabilities, and rate concepts. First known uses appear in scholastic and early modern mathematical treatises where proportional relationships were essential, with English usage evidenced in translations and mathematical dictionaries of that era.
