This is true.
Example:
= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3
= 8/9 * 3/7
= (8*3)/(9*7)
multiply numerators; multiply denominators
= 24/63
simplify
= 8/21
ANSWER: This is (A) true

Part 2) 
Part 3) 
Part 4) 
Step-by-step explanation:
step 1
Find the value of x
In the large right triangle
----> by CAH (adjacent side divided by the hypotenuse)
Remember that
substitute
solve for x
---> improper fraction
step 2
Find the value of z
In the large right triangle
Applying the Pythagorean Theorem
substitute the value of x
solve for z
simplify
step 3
Find the value of y
In the right triangle of the right
---> by SOH (opposite side divided by the hypotenuse)
substitute the given values of y and z
Remember that
so
solve for y
step 4
Find the value of b
In the right triangle of the right
---> by CAH (adjacent side divided by the hypotenuse)
substitute the given values of y and z
Remember that
so
solve for y
