Part 2 (BOB2)

What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests.

  • Some of the mistakes I did was not reading the questions carefully. Some of the questions I got wrong were because I didn't do the math, and I was such in a hurry. Next time I do a math test, or any test, I will study, and take my time to read the questions carefully, and solve them properly using word ratios, ratio tables, etc.

Rewrite 2 questions that gave you difficulty with different numbers.


1. Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

A survey of students in the school found that 18 had Sony phones, 56 had Motorola cell phones, 12 had LG phones, and 26 had Nokia phones.

  • What is the ratio for Motorola phones to the total of phones? Simplify your answer.

a. 56:112 b. 7:14 c. 28:56 d.1:2
