Answer:
A. 4 2/3 hours
B. (i) 9 4/5 hours
(ii) 1 19/30
Step-by-step explanation:
Firstly, to find the number of hours he used in visiting old folks, what we have to do is to multiply the fraction of hours he used by the total number of hours.
Mathematically, that would be;
4/7 * 8 1/6
8 1/6 is same as 49/6
So the number of hours he spent visiting old folks would be ;
49/6 * 4/7 = 14/3 = 4 2/3 hours
B. What we do here is simply multiply the fraction now by what he spent last year.
That would be 1 1/5 * 8 1/6 hours
= 6/5 * 49/6 = 49/5 = 9 4/5 hours
ii) Now we want to know how much more time will be spent this year than last year.
What to do here simply is to subtract the time taken last year from what we have this year
That would be;
49/5 - 49/6 = 49/30 = 1 19/30

Answer:
y=66(.25)x
(obviously the x is supposed to be an exponent but idk how to make it an exponent)
Step-by-step explanation:
When writing fractions in simplest form, there are two rules to follow. First, ask if the numerator and denominator can be divided by the same number. Second, see if at least one number in the fraction is a prime number. We do as follows:
7500 / 320 / 20/20 = 375 / 16
