Margie hiked a 17 7/8 mile trail.She stopped every 3 2/5 miles to take a picture.Which is the best estimate of the number of times she stopped ? A 4. B 6. C 7. D 8.

Answers

Answer:

Option B is the correct answer

Step-by-step explanation:

Margie hiked a 17 7/8 mile trail.

$\texttt{Distance hiked by Margie = }17(7)/(8)=(17* 8+7)/(8)=(143)/(8)mile$

She stopped every 3 2/5 miles to take a picture.

$\texttt{Distance at which she stopped to take picture = }3(2)/(5)=(3* 5+2)/(5)=(17)/(5)mile$

$\texttt{Number of pictures taken = }\frac{\texttt{Distance hiked by Margie}}{\texttt{Distance at which she stopped to take picture}}\n\n\texttt{Number of pictures taken = }((143)/(8))/((17)/(5))=(715)/(136)=5.28$

So she can take maximum of 6 picture and minimum of 5 picture.

Option B is the correct answer

17 7/8÷3 2/5
143/8÷17/5
multiply by reciprocal
143/8×5/17= 715/136= 5.26 which is closer to
B. 6

If 120 marks is 60% what is full marks

Answers

percentage is a value by a fraction of 100.
120 marks is equivalent to 60%
this means from the whole amount, 60 % of the whole amount is 120 marks
we need to find the full marks
if 60 % --- 120
then 1 % --- $(120)/(60)$
full marks are 100 %
therefore 100 % - $(120)/(60) * 100$
100 % --- 200 marks
full marks are 200 marks

since 120 is 60 percent we know that 2/3*120+120 will be 100 percent

2/3*120=80
so 80+120=200

So, full marks is 200

3/2+2x/5=7/10 these are fraction busters but I don't know what I'm supposed to do and what the answer is?

Answers

3/2+2x/5=7/10

We simplify the equation to the form, which is simple to understand
3/2+2x/5=7/10

Simplifying:
+1.5+2x/5=7/10

Simplifying:
+1.5 + 0.4x=7/10

Simplifying:
+1.5 + 0.4x=0.7

We move all terms containing x to the left and all other terms to the right.
+ 0.4x=0.7-1.5

We simplify left and right side of the equation.
+ 0.4x=-0.8

We divide both sides of the equation by 0.4 to get x.
x=-2
