If there were 10 strawberry cupcakes then chocolate would have the same number as 10= 1/2. Then 2/4 can be simplified to 1/2 meaning that Rick are 1/2 of 10 and 1/10 is just one out of the 10 strawberry cupcakes.
Rick ate 5 Chocolate Cupcakes
Steward are 1 Strawberry Cupcake
Answer:
95.1
Step-By-Step Explanation
78:82*100 =
(78*100):82 =
7800:82 = 95.12
Now we have: 78 is what percent of 82 = 95.12
Question: 78 is what percent of 82?
Percentage solution with steps:
Step 1: We make the assumption that 82 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%=82
Step 4: In the same vein, x%=78
Step 5: This gives us a pair of simple equations:
$100\%=82(1)
$x\%=78(2)
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% over x% = 82 over 78
Step 7: Taking the inverse (or reciprocal) of both sides yield
x% over 100% = 78 over 82
x = 95.12%
Therefore, 78 is 95.12% of 82
