### My BOB & Ratio

For homework for today we had to pick one picture and write different kinds of ratios about it.

Ratios:

part ratio = Part to part

3 part ratio = Part to part to part;">Part to total = part to total

2 part ratios:

Blue to Green

1 to 6

Green to Yellow

6 to 4

Blue to Yellow

1 to 4

Part to total ratios:

Blue to total

1 to 17

Yellow to total

3 to 17

Green to total

6 to 17

3 part ratios:

Blue to Yellow to Green

1 to 8 to 6

Green to Blue to Yellow

6 to 1 to 6

Blue to Red to Green

1 to 6 to 6

The ratio that I am going to do is....

Blue to Yellow

1 : 4

B/Y =1/4

0.25

25%

My questions are.....

What would be the ratio of Yellow to Blue to total?

What would be the ratio of Green to Purple?

What would be the ratio of Yellow, Red, Blue to total?

BOB part 2

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 mistakes I made was I did'nt read the questions well enough.

The next time I do a math test I am going to read the question more carfeully, remember to study more Math.

Rewrite 2 questions that gave you difficulty with different numbers.

1)A rapid transit has 17 passengers on it as it starts to run. At the first stop 5 passengers get off and 31 passengers get on. What is the ratio of the number of passengers who were on the train as it arrived in the station to the number who were on the train when it left the station? Express your answer in the lowest terms.

2)Four students are running for student council president. Of 70 students polled, 38 chose Mike, 6 chose Patricia, 14 chose Brian, and the rest chose Karen. What is the ratio of votes for girls to votes for boys in the student council election? Express the ratio in lowest terms.
