3 Questions:

1) What would the ratio be for blue, green, yellow to total?

2) What would the percent, fraction, decimal be for the ratio red, yellow to total?

3) What would the ratio be for red to total in simplest terms?

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.
