TEST CORRECTIONS

My first mistake was on the first section of the test, where the question asks 16/9 - 3/2.
I had converted the fractions into mixed numbers, where I came up with 3 5/18. But the supposed answer is 5/18.

My second mistake was the one that asks, "In computer terminology, a bit is 1/8 of a byte. How many bits equal 16 bytes?"
My mistake was that I went, 1/8 x 1/16 = 2/128. The right answer is 128 bits.

The third mistake I made was the one about Tamar and apple pie.
My mistake was that I answered 1/4. But the right answer was 1/2 x 1/4 = 1/8.

The other mistakes I made were on the bottom where I drew all three pictures wrong, and I got the phrases wrong as well.
The correct answer for the 1st one was, What is 5/6 groups of 1/2?
The correct answer for the 2nd one was, How many groups of 1/3 are in 1/2?
The correct answer for the 3rd one was, How many groups of 1/2 are in 5/8?

The correct answers for the pictures were...
