Simply cross multiply the proportion of
6/27= x/81 do 6•81 divided my 27 for your answer which is 18
Answer:
She can make 34 bows with 10 feet of ribbon left
Step-by-step explanation:
1.5x34=51
61-51=10 feet of ribbons left
51/1.5=x
22÷2/3 =33.000000003-13=20.000000003 (about 20)
check:
20+13=33
33x2/3=22
answer: x=20
9514 1404 393
Answer:
13
Step-by-step explanation:
Let n represent that number.
(2 +n)/(5 +n) = 5/6 . . . . . . . . n is added to numerator and denominator
6(2 +n) = 5(5 +n) . . . . . . . . . multiply by 5(5+n)
12 +6n = 25 +5n . . . . . . . . . eliminate parentheses
n = 13 . . . . . . . . . . . subtract 5n+12
Adding 13 to each term will give 5/6.

<em>Check</em>
(2 +13)/(5 +13) = 15/18 = (3·5)/(3·6) = 5/6
_____
<em>Alternate solution</em>
The difference of denominator and numerator in 2/5 is 5-2 = 3. The difference of denominator and numerator in 5/6 is 6-5 = 1. In order to make the latter difference 3, we must have (3/3)(5/6) = 15/18. We can get 15/18 from 2/5 by adding 13 to numerator and denominator.
