How much of something per 1 unit of something else.
Examples:
• 100 cars pass by in 2 hours. The unit rate is 50 cars per hour.
• You can paint 3 boards in half an hour. The unit rate is 6 boards per hour.
• 200 sausages were eaten by 50 people. The unit rate is 4 sausages per person.
• They need 5 m of thread to make 2 cm of cloth. The unit rate is 2.5 m per cm.
Answer: The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?
From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
Say for example, you have the improper fraction 18/7
The first step is to find out how many times 7 fits into 18
This looks like flipping the fraction, 7/18 = 2 whole times with 4 parts left over
The 4 left over gets put in front of the original number (7) to give 2 4/7
To check if you have done it correctly, multiply the whole number (2) by the denominator ( 7 ) and then add the numerator.
2 x 7 = 14 + 4 = 18
