NO ONE CAN SOLVE THIS, NEITHER CAN YOU :::By what percent will a fraction change if its numerator is decreased by 10% and its de
Veseljchak [2.6K]

Answer:

9/5

Explanation:

original fraction : x/y

new fraction = .9x/(.5y)

= 9x/5y

(9x/5y) / (x/y)

= 9x/5y * y/x

= 9/5

= 1.8

so it increased by 80%

e.g suppose we had 100/200 or 1/2

new fraction = 90/100 or 9/10

new ratio = (9/10) / (1/2)

= 9/5

1) What percent of 440 is 369?
zimovet [89]

Answer:

119.24

Explanation:

Step 1: We make the assumption that 369 is 100% since it is our output value.

Step 2: We next represent the value we seek with x​.

Step 3: From step 1, it follows that 100%=36​.

Step 4: In the same vein, x% = 440​.

Step 5: This gives us a pair of simple equations:100%=369(1) 440(2) = x%

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS(left hand side) of both equations have the same unit (%); we have 100%/x% = 369/440

Step 7: Taking the inverse (or reciprocal) of both sides yields x%/100% = 440/369

Therefore, 440​ is 119.24% of 369.
