How to convert a repeating decimal to a fraction when only 1 digit is repeating?

Alecsey [184]

Example 0.777777

x = 0.77
10(x = 0.77) ----(10 because it is repeating by the tenth digit. if repeating by 2 digits like 0.2828, you'll multiply by 100)

10x = 7.77
-(x = 0.77)
9x = 7.00
x = 7/9

In the number 15.2201 how does the value of 2 in the tenths place compare to the value of the 2 in the hundredths place

lakkis [162]

Answer:

The 2 in the hundreths is 10% of the 2 in the tenths

Step-by-step explanation:

We are given the number 15.2201

#The value of 2 in the tenths:

$0.2$

#The value of 2 in the hundredths:

$0.02$

The difference of the 2 in the tenths and in the hundredths is:

$=2_t-2_h\\\\=0.2-0.02\\\\=0.18\\\\\#2_h \ as \ a \ \% \ of \ 2_t\\=\frac{2_h}{2_t}\times 100\%\\\\=\frac{0.02}{0.2}\times100\%\\\\2_h=10\% \ of\ 2_t$

Hence, the difference between the 2 in the tenths minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.

A(t)=728(1+0.04)^t how much money did Aditya originally invest

Sergeeva-Olga [200]

$728.00 I’m assuming. Because the equation should be A(t)= P(1+i) ^t right? Telling us that P= principal, i= interest & t= time.
I’m assuming from MY financial mathematics class.
