Given that we Jenny wants to equivalent fraction of 45% then convert into reduced fraction and then convert into decimal equivalent.
She has already shown her work. We just need to find the error if any.
to convert any percent value we just divide that number by 100 because percent itself means divide by 100.
Hence first step 45%=45/100 is correct.
Then she needed to convert into reduced fraction. To do that she divided numerator and denominator both by 5 and got 9/20.
step 2 is also correct.
Now she needs to convert into decimal equivalent so she divided 9 by 20 and got 4.5 while the correct answer should be 0.45
Hence she did error when converting fraction form into decimal form.
Answer:
y = 5
z = 55
Step-by-step explanation:
90 - 35 = 55
z = 55
7y = 35
y= 5
It’s B or D , im not that good but I don’t know , so try your best or take educated guess ( or ask a parent )
Answer:
91 grams
Step-by-step explanation:
To get a percentage you go the number which you want the percentage of divided by the full number then multiply all that by 100. For example, (10 / 100) x 100 = 10, so 10 is 10% of 100.
Now lets call the answer x:
(x / 130g) x 100 = 30%
Now you need to get x on its own, so you need to rearrange it:
x = (30 x 130) / 100
When you change the sides, you change the signs.
With this equation we can work out what 30% of 130 is. So,
(30 x 130) / 100 = 39g
So, 39g is 30%. To find out how much sugar is in the diet juice you need to subtract this from the regular cranberry juice sugar:
130 - 39 = 91g
So there is 91 grams of sugar in a serving or diet juice.
