To convert a percent to a decimal you divide by 100
1.6% = .016
You then multiply .016 times 75.20 which is 1.2032
Answer:
a. fly = 5.7
b. fly = 7.5
Step-by-step explanation:
a.
hoist/fly = 1 / 1.9
The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.
1.9 * 3 = 5.7
b.
hoist/fly = 3/5 (this is the new ratio)
4.5 / 3 = 1.5
5 * 1.5 = 7.5
