Students in a cooking class made 4 1/2 quarts of soup. they served 4/5 of the soup to friends. each serving is 3/5 quart. hector incorrectly says that there were 3 3/5 serving of soup. what is the correct number of servings ? what did hector do wrong ?

The correct number of servings of soup is 6.

What Hector did wrong was that he assumed that the total quarts that was served is the number of servings.

The first step to determine the answer is to determine the total quarts of soup that was served.

Quarts served = fraction served x quarts the class made

×

× = =

The second step is to determine the number of servings. In order to determine the number of servings, divide the quart of each serving by the total quarts served.

÷

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
