16.XLII/VII=6
All are right except for 15.
40?
Right!
Thank you!
You're welcome.
Let me explain how to get the answers to each of the equations:
9. To solve XLIV + XXXIX, first convert the Roman numerals to their corresponding values: XLIV = 44 and XXXIX = 39. Then, simply add these two values together: 44 + 39 = 83.
10. In this equation, DCLXXII represents 672 and CCCXCI represents 391. To solve DCLXXII + CCCXCI, add these two values together: 672 + 391 = 1063.
1. D-CLXV = 335. To solve this equation, we first need to convert the Roman numeral D to its value, which is 500. CLXV represents 165. By subtracting the value of CLXV from D, we have 500 - 165 = 335.
12. C-XX = 80. In this equation, the Roman numeral C represents 100 and XX represents 20. By subtracting the value of XX from C, we get 100 - 20 = 80.
13. XV x V = 75. In this equation, the Roman numerals XV and V represent 15 and 5, respectively. To find the product, multiply these two values together: 15 x 5 = 75.
14. VIII x XXX + 240. Here, VIII represents 8 and XXX represents 30. By multiplying VIII by XXX, we get 8 x 30 = 240. Finally, add 240 to the product: 240 + 240 = 480.
15. MM / L = 22. In this equation, MM represents 2000 and L represents 50. By dividing MM by L, we have 2000 / 50 = 40. Therefore, the equation is incorrect.
16. XLII / VII = 6. In this equation, the Roman numerals XLII and VII correspond to 42 and 7. By dividing XLII by VII, we get 42 / 7 = 6.
