Mathematics
1 answer:
kicyunya [14]3 years ago

c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7

Convert mixed fraction into a simple fraction

6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7 

c/7 = 43/7

proportionality: 

a/b = c/d where  cross products are equal :  ad = bc

a = c 
b = 7 
c = 43
d = 7          

<span>ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43</span>

__

You can also work this using improper fractions:

(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)

  = (11×5)/(6×2×5) = 11/(6×2) = 11/12

If 5% of the total sale is 125 dollars what is the value of the ticket sale
RideAnS [48]
So the question is
:
5% of total sale is 125

'of' means mutiply
'is' means equals

percent means parts out of 100
5%=5/100=1/20
so now we have
1/20 times total sale=125
multiply both sides by 20 to clear fraction
20/20 times total sale=2500
1 times total sale=2500
total sale=2500
answer is total sale=$2500<span />
