The two numbers form a comparison: smaller = 1 part, larger = 9 parts.<br><br>
[[model:questions/solutions/q4609.png]]<br><br>
&bull; Total parts = 1 + 9 = 10 parts<br>
&bull; 10 parts represent the sum: 71.5<br>
&bull; 1 part (smaller number) = 71.5 ÷ 10 = 7.15<br>
&bull; 9 parts (larger number) = 9 × 7.15 = 64.35<br>
<br>
The larger number is 64.35 and the smaller number is 7.15.<br>
Check: 64.35 + 7.15 = 71.5. 64.35 ÷ 7.15 = 9. ✓
