Answer:
Sylvia's investment would double first
Step-by-step explanation:
The number of years it takes for amount invested to double itself using the 72 rule is 72 divided by rate of interest as computed below:
Sylvia investment:
Sylvia's investment would double in 9 years' time (72/8)
Manuel's investment"
Manuel investment of $600 would double itself in 9.9 years' time (72/7.25)
From the above analysis,Sylvia's investment of $500 at the 8% rate of interest would double first
3 and 2/5 ÷ 4 and 1/3
The first step before you can divide these is that you must make them improper fractions, they cannot be mixed numbers.
3 = 3/1 = 15/5
15/5 + 2/5 = 17/5
3 and 2/5 = 17/5
4 = 4/1 = 12/3
12/3 + 1/3 = 13/3
4 and 1/3 = 13/3
Now you can divide 17/5 and 13/3.
Step 1- Turn the fraction you are dividing by into its reciprocal.
13/3 reciprocal equals 3/13
Step 2- Multiply.
17/5 • 3/13
17 • 3 = 51
5 • 13 = 65
Answer: 51/65
Step 3- Simplify if possible.
51/65
This is already in simplest form so there is no need to simplify.
So the answer is 51/65.
