1. on monday, cathy read 1/6 of her book, and on tuesday, she read 2/6 of the book. how much has she read? (a) 1/6 (b) 1/5 (c) 1/3 (d) 1/2 2. jack has 4/8 of a pizza left from a party. if he eats another 1/8, how much is left? (a) 3/8 (b) 2/3 (c) 5/8 (d) 1/2 3. how much is 2/3 cups plus 2/3 cups? (a) 1 1/3 cups (b) 1 2/3 cups (c) 3/4 cups (d) 2 cups 4. how much longer than 5/8 inch is 7/8 inch? (a) 1 1/2 inch (b) 1/4 inch (c) 1 3/8 inch (d) 1 1/8 inch 5. plasma makes up 11/20 of your blood, and blood cells make up the other 9/20. how much more of your blood is plasma than blood cells? (a) 1/20 (b) 1/10 (c) 1 (d) 11/20 me this is really !

The answers are (1) D, (2) A, (3) A, (4) B and (5) B.

Step-by-step explanation: The calculations are as follows

(1) Given that, Cathy read one-sixth of her book and on Tuesday, she read two-sixth of her book. So, the total part of the book that she read is

(2) Part of the Pizza left after the party that Jack has is four-eighth and he eats one-eighth part again, then the remaining part of the pizza left is

(3) The total of two-third cups and two-third cups is

(4) Seven-eighth inch is longer than five-eighth by

(5) In our blood, plasma is more than blood cells by

Thus, the correct options are (1) D, (2) A, (3) A, (4) B and (5) B.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
