Hemal wanted to make dessert for her family. The recipe made 8 servings, but she only wanted to make enough for 5 people. If the recipe for 8 servings called for 2 cups of flour, how much flour would she need for 5 servings?
i believe this is ratio and proportion problem
8 : 2 = 5 : x solve for x
you are familiar with that notation right?
not really
what's your lesson?
its a mixture but its fractions
If you write what was written above as fractions: 8/2 = 5/x You can solve for x. Do you know how to do that?
are you sure your lesson is not ratio and proportion?
not really im stuck on fractions
i have no idea how to solve this via fractions except for what i and @ten have said..
Multilpy both sides of the equation by 2. That will remove it from the left side, and you have 5 * 2 on the right side for the numerator. Does that make sense?
@ten i dont think we should be solving this by ratio and proportion if that's not the lesson...
so is it 8*2 and 5*2 as the fraction
2 * (8/2) = 8 The reason you multiply by to is to remove it from the denominator.
oops by 2
Now you should have: 8 = 10/x
so i got 5/16
Did you get to: 8 = 10/x the 16 is not correct. You shouldn't multiply 2 * 8, that 2 just cancelled out the 2 that was in the denominator.
what am i doing wrong
2 (8/2) = 2 * (5/x) Equals 8 = 10/x
i got 4
The next step would be to multiply both sides by x to get rid of it in the denominator on the right side: 8x = 10
Then divide both sides by 8, so that x is by itself: x = 10/8 which can be reduced to x = 5/4
now i got 1.25
That's the same as 5/4
right so i got 1 1/4
That's correct!
